Chapter 14, Problem 47QP

Given the same reactant concentrations, the reaction:

$\text{CO}\left(g\right)\text{ + }\left(g\right)\to {\text{COCl}}_{\text{2}}\left(g\right)$

at $\text{250°C}$ is $1.50\times {10}^3$ times as fast as the same reaction at $\text{150°C}$. Calculate the activation energy for this reaction. Assume that the frequency factor is constant.
