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.

3:52 'everything that happens in one direction happens in other direction' ... 'other direction' maybe a good name for a boy-band.

i know you said on every episode

[@kalielaine2328]

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

[@georgeabreu6392]

Kali Elaine That quality is true for all knowledge though.

[@MohammadBilal-xt2xh]

Basically an outcome of every science course I have taken haha.

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

[@rockercaterrorencountered4924]

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."

My teacher spent around 4 lessons trying to explain this to me and she still failed, you've done it in ten minutes! Thanks guys!!! :D

[@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.

[@chelleloreto]

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!

[@2berrykool]

seriously thank you for your videos I got an 88 on my last exam where the average was at a 68... next exam t-minus 2 weeks and final the week after

When you think he already explained everything there is to be explained, but it turns out to be just the intro :')

[@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!

[@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!

[@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.

[@rachaeldaley8173]

This is the best equilibrium video, I have a Chem test tomorrow and trust me I was so confused. Good Job as usual guys!!

[@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

[@R0ck4x3]

I love watching these videos, so many nerdy references in the little animations, like the Predator in the intro to this video.

[@RabiRose]

Hank, I love that you consistently seem to have what I'm looking for

[@grantdirienzo9965]

I knew the textbook answer for how pressure effects equilibrium, but seeing it in your animation made it actually make sense to me. Thank you!

[@wulf4785]

I cannot stress how much of a help this video and channel are to my grades and life. I could not make AP Chem possible without this content thank you so much!

[@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.

[@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.

[@22453790]

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

[@ECARaviRamyaSree]

Dat one direction reference tho

[@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.

[@seamie6644]

Well, Hank talked about pressure and temperature can change the side of the equilibrium reaction, so how about volume? does it affect too?

[@alysiastringer5610]

volume is the same as concentration which he discusses at the start...

[@GhastlyDesigns]

NIGIHAYAMI Kohaku Nushi Pressure and volume are inversely proportional according to Boyles law (Decrease volume, increase pressure). If you decrease the volume, it's expected there will be more collisions between the particles and the wall of the container. Therefore it will increase the pressure within the container making the system favour the reaction with less particles to get back to equilibrium. It's also good to note that concentration is directly proportional to pressure, so if the pressure increases; so will the concentration...and volume will decrease (because it's inversely proportional to pressure). :)

[@seamie6644]

GhastlyDesigns how can I forget about Boyle's? So stupid of me! Thanks anyway :)
