Equilibrium: Crash Course Chemistry #28

In this episode of Crash Course Chemistry, Hank goes over the ideas of keeping your life balance... well, your chemical life. Equilibrium is all about balance and today Hank discusses Chemical Equilibrium, Concentration, Temperature, and Pressure. Also, he'll chat about Le Chatalier's Principle and Fritz Haber.

The more you learn about chemistry, the more you realize what you previously knew was wrong.

[@MohammadBilal-xt2xh]

Science is the only subject which allows you to use your imagination, don't spoil it by cramming.

[@rockercaterrorencountered4924]

Science is the only subject that allows you to use your imagination? What about English? Art? I like science as much as the next guy, but that statement was more than a bit off.

Dear Crash course, I'm in my final year of schooling and I'm actually not sure when exactly I started to watch these videos but y'all have been incredibly helpful throughout my years of school. From the bottom of my heart, thank you so very much ❤️

[@ximenam.9236]

I love how I'm cramming for a chem 2 test tomorrow and I'm focused, then he says one direction and in the corner of the screen is a one direction concert going on, now there is a concert in my brain.

A quote from chemistry that pertains to lived life: "Equilibrium isn't about staying the same all the time; it's just about keeping your balance as your circumstances change."

I let myself get so behind on Chemistry lectures at uni that I'm now basically teaching myself 4 weeks' worth of content lol. Thanks so much for your videos, guys, here's hoping I get through the exam in a month's time cos right now I wouldn't understand most of it!

[@alyssaalcantara6739]

I love learning while being entertained by his creative analogies ☺️

[@alyssan6800]

Hey Hank, you know what would be awesome? If you could do a series on Physics *insert excitement*. Your chemistry videos have helped me so much!

[@sherripy3932]

I swear it is not even funny how much your videos are helping me with my chemistry class. I'm studying for my last test (tomorrow) and looking over the homework packet(which i did not do) i realized that I know absolutely NOTHING!!! But watching these videos make everything a LOT easier! I cannot thank you enough for making these videos! I am so grateful to you!

[@PowerWillful]

Fun isn't something one considers when balancing the universe. But this... does put a smile on my face.

[@22453790]

This cannot have come at a better time. I have a chemistry test on equilibrium tomorrow. Thanks soo much crashcourse

[@waynasattar2991]

So much to say: 1) I love how there's a variety of classes on Crash Course. 2) Bless Hank for making me less stressed with all the sarcasm and light jokes. I love how he does that. 3) A request: Could you please do a video on the Contact Process for manufacturing Sulfuric Acid? THANK YOU

[@talhotbrunnette123]

I love this guy, totally saving me on these damn conceptual questions on the exams. Thanks friend

[@ahmedkh1900]

seriously!!

[@shirubionicle]

why isn't there a crash course physics channel?? this is a question ive been asking since da beginning of time XD.

[@JTan-wu7wg]

+Shriram Raveendran Don't know. Probably because CrashCourse tries to fit everything in around ten minutes. Physics, I assume, needs more time than around ten minutes.

[@JTan-wu7wg]

Gunbnelch Maui Yea. I'd usually watch CrashCourse in junction with Khan Academy and Bozeman Science.

[@shereitograce7844]

+Shriram Raveendran I would totally watch that so hard.

[@airro3672]

Physics = Brightstorm. Chemistry = Crash Course. Biology = Bozeman

[@arousedsquirrel2429]

+Gunbnelch Maui Khan could explain what he waists 10 minutes on, in at least half that time.

[@pete8420]

Thank you for your videos! My chem/bio teacher left my school and was replaced by a teacher that doesn't appreciate those who have more visual and pattern thinking minds, so I'm glad I can still pay attention to these.

[@SuperSox97]

I applaud you two for having a debate so intelligent and devoid of hostility. I found it very interesting to read through it, and I'm glad to know that there are people on the internet that can intelligently discuss subjects (especially ones like global warming and starvation) without raging at each other.

[@kashshk845]

i love how im casually revising, watching crash course to actually understand chemistry and then obviously ONE DIRECTION, why dont them lads leave me for a second to focus IM SHOOK

[@johnobrien5464]

This reminded me of when I was in chemistry class and they began to say how everything that we he previously learned was wrong or at least different to what we had learned in the more general science classes we had had before. Also I had a student teacher that did that reaction and showed us Crash Course

[@JulieGilbert]

Great Video. You should read Master Mind (The Rise and Fall of Fritz Haber, The Nobel Laureate Who Lunched the Age of Chemical Warfare). A very interesting book.

[@apsanders9359]

Thanks for the video and all the other awesome videos! However, there is an issue with the concentration vs time graph around 3:15. The change in concentration should be the same as the stoichiometry ratios. I realise the y-axis has no scale but I think it is still a relative scale and probably needs to reflect the 1:3:2 ratio of the equilibrium equation.

[@parissitzoukis2919]

this is fire 🔥 🔥 damn love it

[@harleyquinnwastaken]

Generally - Increased concentration moves the system in the opposite direction, Increased pressure moves the system to the side with the fewest gaseous moles, And increased temperature moves the system in the endothermic reaction. (The reverse is true for each statement.)
