Wow, Sal after all these years I now see how rate and equilibrium are related! It just was taught together assuming they were ralated. Way to put things in perspective. This is WONDERFUL!

@fosheimdet If there is 1 mol of a substance you could not find an infinite number of molecules, since 1 mol is 6.022*10^23 molecule /mol. you could find an infinte amount of reaction forward and backward if you had the right temp pressure and time.

[fosheimdet]

so that means that if the concentration of a substance is 1mole/liter, the chance of finding infinite molecules of that substance in one liter is: (1mole/liter)^infinity=1

that doesn't seem to make much sense...

@unitednerdsbeproud you can. and you will get what you expect.

If theres a Reaction: (you may take any co-efficients):

3A + 2B turning into 3C (and vice versa); having equi. constant as [C]^3/[A^3]*[B]^2

Then...

if you go reverse or reciprocal it, that is- [A]^3*[B]^2/[C]^3

then you'll get equi constant for the reaction:

3C turning into 3A + 2B (and vice versa)

Its nothing "sacred" that its :forbidden" to reciprocal it.... its just what you expect to get.... the constant for reverse order.

@hellokittydimaggio this guy needs to be the president of UN (do they even have one??)

[JayantKumarZ]

not only how the equilibrium... but the rate constant and the entire "law of mass action" (of which none knows anything about, than just plugging the numbers.... except a very few, ofcourse I mean those who have seen this video...)... was also created from the very same logic!

I cant believe such a powerful discovery was lost, and not even any of the internet had 'any' information of how it was derived!

And now we see it being "re"-discovered from the "scratch"....

I say you should be in NASA!

200 dollar textbook, and I understand this after watching a free video...great.

Reminds me about CHANNEL [V] ...

can you please make a video to explain equivalent weight pleasseeeeeee :)

this guy needs to be writing our text books.
