Chemistry | Chemical Change | Chemical Equilibrium Graphs

This video covers the effect of concentration, temperature and pressure on equilibrium by applying Le Chartelie's principle.

I'm literally writing chem tmr and I had NO IDEA what was going on in these graphs (and lowkey everything else, don't tell my teacher) but you make it so easy to understand 😫. thanks sm sir, you're working miracles over here 😘

[@calvinbafshoe2626]

Couldn't agree more with you sir it is really quite a challenge to teach chemical equilibrium graphs. I've been wondering how am I going to tackle this and best present it to my learners so that they will understand it.

[@MlungisiNkosi]

Mr Bafshoe, the reality is there will always be sections or part thereof that are challenging to tackle. But that's why we're there for each other, to help point one another to greener pastures. I will also rely on you to share any simpler method you may develop in tackling some of the other sections. We are in this together... For the love of Physical Science and the betterment of our people. Hoopaaa!!! Lol

[@calvinbafshoe2626]

So, concentration and pressure happen concurrently? Cause this was confusing me. I know that when the volume is decreased the concentration increases from the equation or rather from the definition of concentration however I also know that pressure will increase because number of collisions per area increase as well and so i really didn't know how to represent it on the graph.

[@MlungisiNkosi]

Yes sir. The two are related, particularly because of the c=n/V equation.

Danko Malume❤️ Sir at t2,if asked why the Hydrogen decreased as the concentration of nitrogen was added,how can I explain it ? If it correct to just say 'the forward reaction is favoured" ?

[@MlungisiNkosi]

You’re correct… the forward reaction was favoured. That means hydrogen and nitrogen are used, hence they decrease

[@youngarrogant6172]

You said equilibrium shift to the left?😑

[@mildredagu8028]

Hello sir How do you know if a reaction as a whole is exothermic or endothermic without them giving you an enthalpy

[@MlungisiNkosi]

Yes… you’d have to be given other sets of information to conclude that it’s either endothermic or exothermic

[@mildredagu8028]

@@MlungisiNkosi okay sir I have another question....is it safe to say that a decrease in your kc value will always mean that your reaction as a whole will be exothermic?

good evening , why wont we start at zero , for hydrogen and nitrogen

[@MlungisiNkosi]

They are reactants... We cannot start with nothing and end up with something.

[@cm-co9sd]

would the H2 not be higher on the graph due to it having a 3 in front of it?'

[@MlungisiNkosi]

The stoichiometric coefficients are not in any way an indication of actual moles that are places in the reaction... Therefore,you may easily find a lower concentration of H2 or even a higher one. It all depends on the person conducting the reaction. The coefficients, however show us the ratios in which they will collide (react) with each other. I hope that makes sense...

Sir is there a difference between dynamic equilibrium and chemical equilibrium?

[@MlungisiNkosi]

Nope... It's the same thing

[@melikhayakepu6163]

@@MlungisiNkosi actually There is a difference between chemical equilibrium to a very small extent, dynamic equilibrium tells us that the reacyion still CONTINUES woth the rate of reactants and products being equal at contant concentration. While chemical equilibrium misses the contiue part of it but the assumption is thst though thate is the same but it should be continuing, so Dynamic is explicitly mentioning that at eauilibrium the reaction still continues.

sorry a little confused about the last part when pressure is increased that means the volume decreases right so according to Le chateliers principle the system will favour the reaction that decreases the pressure which means volume increases therefore the reaction that produces more gas moles should be favoured to oppose the disturbance or Am I wrong? I think Sir made a mistake. 💁‍♂💁‍♂

[@kgalanelucasmalekane8320]

Sorry about that I made a mistake fewer gas moles would decrease pressure and not the other way around so sir is absolutely correct. Forgive me Chemistry can be confusing sometimes 🙃🙆‍♂🙆‍♂
