Solution

A. The rate constant decreases.

This is because the rate constant (k) and the activation energy (Ea) have an inverse relationship according to the Arrhenius equation: k = Ae^(-Ea/RT), where A is the pre-exponential factor, R is the gas constant, and T is the temperature. As the activation energy increases, the rate constant decreases.
