In the Arrhenius plot of \( \ln \mathrm{k} v \mathrm{~s} \frac{1}{\mathrm{~T}} \), a linear plot is obtained with a slope of \( -2 \times 10^{4} \mathrm{~K} \). The energy of activation of the reaction (in \( \left.\mathrm{kJ} \mathrm{mole}^{-1}\right) \) is \( \left(\mathrm{R}\right. \) value is \( 8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1} \) )
