Question:
The rate constant (k) of a reaction is measured at different temperatures (T), and the data are plotted in the given figure. The activation energy of the reaction in $\mathrm{kJ} \mathrm{mol}^{-1}$ is :
( $R$ is gas constant)
Correct Option: 1
Solution:
Slope $=-\frac{E_{a}}{R}$
$-\frac{10}{5}=-\frac{E_{a}}{R}$
$\mathrm{E}_{\mathrm{a}}=2 \mathrm{R}$
