Dear Paul + your esteemed audience, First of all, many sincere thanks for your collective efforts! You attempt to explain Gibbs Free Energy. You begin by using three spontaneous reactions to explain how a change in enthalpy, entropy and temperature can affect the free energy of a system. You then apply this concept to cellular respiration and photosynthesis. ...sounds terrific, but even big scientific research workers' brains had and still have to stumble herewith... In fact, Prof. Gibbs had learned what ENTROPY exactly IS while attending chemical thermodynamics lectures by Prof. Horstmann in Heidelberg, whereas Prof. Horstmann was one of the very students of Prof. Clausius. Prof. Gibbs was duly heading for the proper embodiment of the Clausius-Horstmann ideas (in fact, Carnot-Clausius-Horstmann ideas, to be correct!), but he had not enough time for accomplishing this, to our sincere regret... Dr. George Augustus Linhart was one of the very rare true followers to Prof. Gibbs, but he had very bad luck... ...It's a truly long and interesting story - hence, some kind of a concise clarification ought to be urgently necessary! So, captain, AHOY! A. There is ONLY ONE BASIC, fundamental Energy Conservation and Transformation Law. It is definitely unique and conceptually indivisible delivering two logically joint concepts - these are Energy Conservation - and Energy Transformation. Still, a more-then-100-years-old conceptual failure has brought us to two separate thermodynamic laws - but this has nothing in common with the actual physics. To come back, they have coined two more fake thermodynamic laws, employed the Probability Theory + Mathematical Statistics, and this has helped formulate the Quantum Mechanics, which is thus a basically metaphysical conceptual construction - and, hence, ought to be only restrictedly fruitful. B. By dividing the basically indivisible law, you are touching Combinatorics, you are touching Probability Theory, you are even stepping back to Thermodynamics for a while, but... You are NOT answering the poser: WHAT IS ENTROPY, sorry! 1. In the formula S = kB * ln(Ω) you do imply, Ω means not a "Huge Number of Microstates", not "Probability", which numerically ranges between [0,1], not even "Wavefunction", which ought to be a purely metaphysical notion, as it is... In effect, Ω ought to be a simplistic algebraic function of Lord Kelvin's Absolute Temperature. This result has been published 100 years ago in JACS by Dr. George Augustus Linhart. 2. WHAT-ENTROPY-IS-poser has been answered not by Clausius, not by Boltzmann, etc., but by Goethe, who has introduced Mephistopheles, the philosophical embodiment of ENTROPY. 3. Newton did basically know WHAT ENTROPY IS - A Counteraction. 4. That Counteractions do not grow to infinity with the growing Actions, but MUST reach their MAXIMUM values, is the result by Nicky Carnot, which has been formalized by Clausius... 5. In effect, J. W. Gibbs Free Energy formula: (ΔG = U + pV - TS, .i.e., ΔG = H - TS, where U is the internal energy (SI unit: joule), p is pressure (SI unit: pascal), V is volume (SI unit: m3 = m*m*m), T is the temperature (SI unit: kelvin), S is the entropy (SI unit: joule per kelvin), H is the enthalpy (SI unit: joule)) renders implicit the interplay among ALL the relevant Actions (the Enthalpic term) and ALL the pertinent Counteractions (the Entropic term). 6. The standard approach you are reporting about is OK for the implicit Enthalpy-Entropy picture, employing it, e.g., for studying reaction mechanism details is likewise eating soup with a fork. The above is about "Entropy" in Physics, Chemistry, Biology, etc., etc., etc. ... Entropy in other fields: Be aware of a powerful trend to build up misnomers in many other fields, for Entropy is the proper term solely for the "Energy Transformation", whatever nature/origin this energy might be of. The Arrow of Time: This is not due solely to Entropy, but owing to Eternal Entropy-Enthalpy Compensation. This is why, the Heat Death morons are proclaiming over and over again ought to be just a useless legacy.
@evgenistarikov3386 Жыл бұрын
Most important addition to the above ought to be the notions of Potential and Kinetic Energies. Potential Energy: a kind of money on our bank account. Where does it come from? More general: Potential Energy in any system does come from interaction among the subsystems of the system. Moron textbooks try to persuade you of "isolated systems" - do never believe such fiddlesticks! Everything is more or less correlated in the Universe. Potential Energy is transformable into Kinetic Energy. Kinetic Energy: the EFFECT of money on our bank account. Its ancient name - VIS VIVA - i.e., the livening/driving force. THIS is about ENTHALPY. Any EFFECT/ACTION MUST DEAL WITH COUNTERACTIONS: obstacles, hindrances, resistances... THIS is about ENTROPY. THIS is just what J. W. Gibbs Free Energy formula renders implicit. If you would not like 'eating soup with a fork', you must consider ENTHALPY and ENTROPY explicitly,🧐

AP Chem student here. One thing that is commonly misconstrued is that breaking bonds releases energy, as you implied around 7:50. Energy is absorbed to break the bonds of the glucose, and then energy is released again when the bonds of water and carbon dioxide are made. The energy released when making bonds of water and carbon dioxide is larger than the energy absorbed when breaking bonds of glucose - that is why energy is released, not because breaking the glucose bonds releases energy. Am I right, or have I confused something?

Alright, imagine throwing a party. Gibbs free energy is like a party budget. If the budget is negative, it means your party is happening spontaneously - people are excited and things are happening on their own. If it's positive, you might need to put in some effort (add energy) to get the party started. If it's zero, the party is in a balanced state. So, in chemistry, a negative Gibbs free energy means a reaction can occur on its own, while a positive value may need a push, like adding heat or other energy. It's all about the energy dance at the molecular party!

Don't get misguided! Total energy remains constant, as explained in the "ball rolling down" example, it's true that the gravitational potential energy decreases as the ball moves down and also not to forget the ball speeds up the moment it comes under motion and hence the kinetic energy increases as it rolls down. Total energy is the sum of kinetic and potential energy. To conclude as the potential energy decreases, the kinetic energy increases and thus the total energy is conserved.

@thomasjohnson80910 жыл бұрын
The whole point of the lecture is to explain what usable energy is, and when it becomes available or gets 'used up'. When the ball goes down the slide it does lose usable energy because the friction forces that decelerate it dissipate the energy through out the metal structure of the slide, which then gets transferred to the earth and gases in the atmosphere (since metals transfer heat efficiently). This inevitably dissipates from the earth as blackbody radiation and is spread throughout the universe, thus being rendered unusable...for now.
@shoot99110 жыл бұрын
Tom Johnson You took the (Delta)G of 3 different reactions.... What?? Isn't that an improper usage of the equation? The gravitational potential energy in the ball on the slide is CONVERTED to kinetic energy. No actual change in energy of the ball other than maybe friction but it is negligible because the diagram in the diagram shown the ball stops also in a rotatory object such as a sphere because the ball is not slid along the slide it spins along the surface. I think what you were trying to explain is that (delta)G is the energy that you get from taking the potential energy of an object and using it and then converting it back. I have never studied Gibbs or have even heard of it but I think I got the concept better from what I learned here better than the average viewer because it was not explained in the most basic sense in enough detail. But I could be just as easily be very wrong. You explained the concept well but there is no continuity in the explanation of why... Only this is how things are. I dont know how anyone can learn why the equation works, if it is not explained. Also I am only 17 years old and am surprised that this is not caught by many more viewers.

So how exactly does Free energy differ from potential energy? I'm having a hard time wrapping my head around why free energy being less than zero makes a reaction spontaneous. If there is no free energy to cause a reaction, shouldn't''t the reaction therefor not happen? Likewise, if the Free energy is greater than zero then the reaction is endergonic, meaning it consumes energy? I think i'm missing something. Great video though.
@TMPChem7 жыл бұрын
Hi William. The definition of free energy as [G = H - TS = U + PV - TS ] looks quite non-intuitive and intimidating, but once you work through a bunch of derivations, you can show that if delta_G is negative during a process which occurs in a closed system at constant temperature and pressure, then that process will also increase the entropy of the universe, and thus that process will be spontaneous, as it does not violate the second law of thermodynamics. The value of negative delta_G during a (closed system, constant T and P) process also indicates the maximum amount of useful work which can be extracted from the system during that process (without violating the second law of thermodynamics). For example, if a reaction inside a battery produces 1 Joule of free energy, then the most work that battery can do (powering a laptop, accelerating a car, etc.) is 1 Joule of work.

Actually, the breakdown of ATP requires an input of energy (all breakages are endergonic). The formation of ADP and Pi, by hydrolysis, is, in fact, what realeases a greater amount of energy (molecules formations are all exergonic), so that the net delta G becomes negative.

Hi there. Really great video which forces me to figure out something that I could not understand previously; that "Gibbs Energy" (and I suspect Helmholz energy too) is a proper title for chem reactions, whereas "work" = dW = pdV is a more suitable term for an engineering process!!! Please, confirm if I am right. Now, allow me to make a comment and set a question. At 11:45 you state ΔG < 0 is the energy from the sun and you imply that this is Gibbs free energy. But I think that (according to the previous diagram and your spoken words) this energy is called the "Activation Energy" which we get it from the sun. You state: ".... Now where do we get the activation energy? In photosynthesis, we get it from the sun!". I think that activation energy has nothing to do with Gibbs free energy. This has to be just the so described "Activation Energy". Unless, of course, we perform integration under the whole curve as follows: ΔG = integral(Free Energy* dReactionProcess, limits: G_start, G_end), where dReactionProcess -> infinitesimal ReactionProcess. In this case, yes, we take into account Activation energy, and goes embedded to the final ΔG. In both reactions (respiration and photosynthesis) it is not quite clear if we take into account Activation Energy while calculating ΔG. But I think that what matters is just the initial and final values of Gibbs free energy. ΔG just equals to G_end - G_start, that is, ΔG = G_end - G_start, where no activation energy is been taken into account in both processes. This is what I vaticinate. Is this correct? Thank you very much.

I appreciate the effort you put into this video; however, as a student that was always confused by this in lower level science courses, it might help if you corrected a few things or went into better detail. You should really talk about the breaking of bonds being endothermic and the formation of bonds a exothermic .. and then show that the formation of bonds releases more energy than the intake of breaking bonds requires energy. If you do this there will be less confusion. Here, you are being vague and implying that exothermic and exergonic reactions are the same. In fact, you and I know they are not. Energy release and spontaneity are not interchangeable, solely related. It only works in the glucose example because the enthalpy is negative and the entropy is positive. Maybe you could go into better detail? Then your students would not need to memorize but they could grasp the concept for a full understanding of what it going on in your examples. Also, a ball rolling down a slide is not the best example. Although it was a good attempt at explaining change in total energy of a system or change in enthalpy, the change in Potential Energy is a conversational force, therefore the total energy is conserved (going into friction/kinetics) and the total energy of the entire system (in this case it would include the surroundings of the ball) because it is quite open a system. Furthermore, if you want to explain it in a better format but still use the 'ball rolling down a slide' example, you could use the Potential energy difference between the initial state of the ball at the top of the slide and the final state of the ball at the bottom of the slide. As the final PE-initial PE = change in Enthalpy for a reaction or Process. Enthalpy speaks of energy in states of some process and/or transfer. I propose you try to explaining this in the form of a hot cup of coffee (with a closed lid; resulting in no flow of steam/matter into its surroundings): the energy of this closed system can flow from a hot concentrated cup (low Entropy) out into the open surroundings (higher Entropy --higher dispersion of heat="disorder"). The Enthalpy of this system (inside the cup) is going from a state of high heat to a state of low heat at a constant pressure. The heat transfer in the"cooling" of the coffee would satisfy the example of enthalpy. And in this example Enthalpy is negative and entropy is positive, making the total free energy of the process go down. Also, Energy never really gets used up, it is always converted and/or given off into another form of energy. Like caterpillars and butterflies. And KUDOS on the explanation of the Gibbs free energy equation!

- Kinetic energy (KE): it is energy stored in the motion of the object (the ball in this case). At the start the ball has no speed. KE = 0. The ball has its KE going up while going down the slide. However as the ball stops at the end, the KE decreased again until it is equal to 0. So globally, the KE of the whole process is equal to 0. - The potential energy (PE): is equivalent to the interaction between the ball, and the other masses surrounding. The main PE source is the gravitational force.
