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. -- TABLE OF CONTENTS Equilibrium = Balance: 0:19 Chemical Equilibrium: 1:25 Le Chatalier's Principle 4:37 Fritz Haber 5:31 -- Want to find Crash Course elsewhere on the internet?

"Equilibrium isn't about staying the same all the time, it's just about keeping your balance as your circumstances change" As someone who is trying at 31 to stop living his life in extremes (used to be a stoner, now I smoke 0 weed; used to have a 1.02 GPA and all the fun, graduated with a 3.96 and 0 fun), you have no idea how much this quote means to me. I'm going to print it out and pin it to my bulletin board!

6:45 But... if you take the product (ammonia) away from the reactants, wouldn't they break down anyways? Or they break down in the presence of the reactants only?

ap exam in a little over a week and our teacher isn't going to have time to teach us the 6th unit, so we have to learn it independently... I'd be dead w/o you, Hank <3

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.

Ah, you might call it "Equilibrium chemistry", but I, I call it Thanos Chemistry, perfectly balanced. Thanos cuts concentration in half, to restore equilibrium :P

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

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!
Fresnido Elnido (8 months ago)
how did it caused an explosion? for me as far as I know, the chemical reaction between the nitrogen gas and the hydrogen gas will produce heat because bonds are being broken and new bonds are being formed.. is it enough to produce an explosion????

then why rich people becomes richer and the poor people becomes poorer? Where is balance here?
Casey C (9 months ago)
Can someone reexplain how temperature affects equilibrium? 😟
namjoon's onion (9 months ago)
@Casey C Ooooo Thank you😁💜
Casey C (9 months ago)
Say for example there's an exothermic reaction and it is heated. The equilibrium shifts to the left/endothermic/reverse (reactants) side to remove heat and hence the reactants increase and products decrease
namjoon's onion (9 months ago)
@Casey C Ohhhhhhhhh
Casey C (9 months ago)
namjoon's onion thanks but I understand it a bit more now. So when the temperature increases the equilibrium shifts to decrease temperature (the endothermic direction) to remove heat. When the temperature decreases, the equilibrium shifts to increase temperature (exothermic direction) and replace heat.
namjoon's onion (9 months ago)
Here's what I thought: Increasing temperature increases the Kinetic energy of the molecules and thus the reactions is more active and proceeds to form the product(the left side)
