### 15.61

How is the equation listed in the answers derived?
I understand it's from lnk=-Ea/RT with changes in T, but my question is where did lnA go?
Thanks!

We didn't go over this derivation and also are not responsible for knowing it.

The change in T can be derived as the two ln equations subtracting from each other.

Which means that the lnA cancel each other out when the two equations subtract from one another.
