The time taken for half of the initial amount of $\mathrm{N}_2 \mathrm{O}_5$ to decompose is $12 \mathrm{~min}$ at $310 \mathrm{~K}$ and $2 \mathrm{hrs}$ at $300 \mathrm{~K}$. The activation energy of reaction in $\mathrm{kJ}$ is $\left(\mathrm{R}=8.3 \mathrm{~J} \mathrm{~K}^{-1} \mathrm{~mol}^{-1}\right)$
