Which is which k?

How do you know which is k' or k if the homework problem doesn't specify which is the forward or reverse reaction??

I think normally we would assume that k is the forward reaction? But I am not positive! They should give it in the problem on the final, though.

In all of Lavelle's lectures it was always k is the forward reaction and k' is for the reverse! I don't think he would change that for the final

It shouldn't matter. As long as you make sure to make the T' and k' line up correctly in the formula. -Ln(k'/k)=Ln(k/k')

As long as you are consistent with what temperature you assign the k's, then it shouldn't matter.
