Chemistry - Chemical Kinetics Question with Solution | TestHub

According to Arrhenius equation, activation energy $\left(E_a\right)$ and rate constants $(k_1$ and $k_2)$ of a chemical reaction at two different temperatures ( $T_1$ and $T_2)$ are related as $$\begin{array}{rl}\ln \frac{k_2}{k_1}& =\frac{E_a}{R}\left(\frac{1}{T_1}-\frac{1}{T_2}\right)\\ & =-\frac{E_a}{R}\left(\frac{1}{T_2}-\frac{1}{T_1}\right)\end{array}$$
