Q:

A particular reaction can be simplified to the following form: A -> B + Heat (i.e. an exothermic reaction). Assume that the reaction occurs in a closed environment. Say that the forward rate of the reaction is k₁ and the reverse rate of the reaction is k_-1. If temperature of the system was decreased, what would be the expected effect on k₁ and k_-1?

A

k₁ increases, k_-1 decreases

B

k₁ decreases, k_-1 increases

C

Both k₁ and k_-1 decrease

D

k₁ and k_-1 remain constant.
