Q. In terms of Arrhenius equation, $ k=A{{e}^{-{{E}_{a}}RT}} $ the temperature dependence of rate constant (k) of a chemical reaction is written. Then, the activation energy $ ({{E}_{a}}) $ of the reaction can be calculated by plotting.

Solution:
According to Arrhenius equation, $ k=A{{e}^{-{{E}_{a}}/RT}} $ $ \text{In k = In A-}\frac{{{\text{E}}_{\text{a}}}}{\text{RT}} $ or $ \log k=\log A-\frac{E}{2.303RT} $ Hence, E is calculated with the help of slope.
