Textbook problem 5G Q5

[Ava 1D]

Hi! Can someone please explain how they solved for part B and C?

[Phoebe 1H]

Yeah, I had the same question...I don't know how to tell what flask is at equilibrium or not either (for part a). How can one tell?

[Phoebe 1H]

I actually just realized that we technically don't need to know this for the midterm since it isn't listed under the problems that we need to know -- it's only 5G 1,3,7,9,11...but it still would be nice to know why this works!

So I think it's flask 3, because each flask is supposed to be a snapshot in time. In flask 3, the concentrations of couples and uncoupled atoms remain the same as in flask 4, so equilibrium has probably been reached in flask 3.
