When to use cis and trans?
Sorry if this is a really dumb question, but I am confused when we use cis and trans when naming. Could someone explain it for me?

Re: Slow Reaction
I believe you use the pre-equilibrium approach only when the fast step is first!

Re: W versus S
I was confused by this as well, thank you for the explanation. So S is essentially related to W in that in order to measure the total disorder we must know the W, right?

Re: HW 8.53
So essentially no heat leaves or enters the calorimeter, it is just that the heat is absorbed or given off within the isolated system? Please correct me if I am wrong, I was a little confused by that as well.
