### 15.61

I was wondering for why in the solutions to 15.63 it says K = k'/k

I thought K = k/k' always. Can someone explain?

The equation is represented as lnk2-lnk1=Ea/R(1/T2-1/T1).

K does infact equal k over k prime, however in this case we are using the arrhenius equation manipulated so that lnA is removed.

You can review the tectbook also. Page 642, shows the different derivations of the arrhenius equation.

I think that when you look at K it is K = k/k', but when you are looking at ln then it is ln(k'/k)
