Chemical Equilibria and Reaction Quotients
Many chemical reactions don't just go one way, they go forwards and backwards. Once there is balance between the two, this is an equilibrium. And we need to be able to predict how much stuff there will be at equilibrium! Get ready to bust out those ICE boxes, folks.

Thank you so much Professor Dave. The most unique thing about your lessons is...there is always a comprehension check test at the end of it. It makes a significant difference because most of the time, I have been watching all online lessons and I thought I understood, but when it comes to problems, I dont know how to use the theory I learnt. But now, with your videos, I can learn what kind of problems will come up for the theory I learnt which is very helpful. Thanks again.

It's always crazy to see just how quickly and thoroughly you can teach a whole concept in under 10 minutes. Amazing work
I love that you are able to present concepts in a way that makes sense. A lot of professors jump into certain topics without really letting us know the importance of it, what its used for in or why we should care. You have an amazing gift of giving students the AHA moment and making things click! Thank you doesn't suffice for the work you do. Much love 🤗

Prof.Dave, You explain everything so well. Guys, everyone watch the ad completely without skipping. This way, the prof gets some money. Thanks a million!
Thank you so much for explaining this concept. You are superb and amazing
Profesor Dave, your on line classes are helpful even to some teachers and professors. Your explanation is absolutely understandable. Thanks

Hello, On the checking comprehension why is [NO2]^2 changed to 4x^2 and not 2x^2? Is it because of the equation give?
@ProfessorDaveExplains
7 жыл бұрын
don't forget that when you do (2x)^2 the exponent operates on both the 2 and the x! so it becomes (2^2)(x^2) or 4x^2

proffesor Dave you really exactly teacher who should all students rely on your lessons shorts and clear and convincing. i really appreciate you professor , but only few topics i didn't get on your lessons. that's Nervous system. CNS and PNS
Can I ask something? What if the K is greater than 1 but the product is a solid. Is it still product favored?
thanks
good method for explanation
This is fifteen times more useful than anything my teacher taught me, lol
Your way of teaching is awesome 👌 sir. I like it. I am from India.
Hey Professor Christ. Suppose If I take the equation of PCl5 PCl3 and Cl2 at 1:44 . Now, since Kc(equilibrium constant) is independent of initial concentration, I can take Z molar solution and should still get the same answer. But if initial concentration is Z and degree of dissociation is a , Kc comes out to be (Za)^2/(Z-Za) => Za^2/(1-a). That is, it depends on Z(initial concentration) . PLEASE HELP.

You can learn as much about chemistry from this man's youtube channel as you can at a four year university.
content so good my chem 2 prof sends your videos to watch instead of him lecturing
Thank you very much this is extremely helpful. However, I am confused about how you got 4x^2 in the numerator when solving for X using the Equilibrium Constant Expression. Could you explain why we use 4x^2 instead of 2x^2? Thanks again!

Hi, do someone know why in the formula "C" is raised to "c", "D" to "d" and so on? and why C is multiplied by D and A by B, before division.

Hi professor Dave. Thanks again for the great videos. Quick question on the checking comprehension. Did you multiply both sides by negative one to get to the quadratic form? When I multiply both sides by the denominator, I get the opposites for addition and subtraction.
@ProfessorDaveExplains
6 жыл бұрын
nope i just brought the left side to the right side! if you have 0.036 - 0.36x and you bring it to the other side to be with 4x^2, you have to subtract the number and add the x term so the signs reverse.

Hi Professor Dave, for the answer 0.12, I know in the table it's 2x so 2 * 0.06 would be 0.12, but the question asks for NO2 while in the table is the concentration for 2NO2 so shouldn't that be divided by 2 again and get 0.6 (NO2) as the final answer? Sorry for my bad english
