Expert Solution
Step 1: Introduction to the given problem

Arrhenius equation: Arrhenius equation give the relationship between the activation energy and the rate constant of a chemical reaction. If we know the value of the rate constant at two different temperatures, we can calculate the activation energy by using the Arrhenius equation.
