### Derive

How can you derive ln(K1/K2)= -delta H/R (1/T1 - 1/T2) from the Van't Hoff equation given on the formula sheet: lnK=-delta H/RT + delta S/R ? Thank you in advance.

See your class notes. I did this step by step in class.

it honestly would probably be easier to just memorize it than try deriving it during the test

Agreed. My TA recommended us know the process derivation of course but he also said not to depend on just the derivation on the exams as they would take up time. Just focus on the final formula and we should be good

In theory we should know how to derive it but no test/exam question has ever had us derive an equ before.
