(i) and (ii) are 2 chemical reactions carried out at TK.
(i). $\mathrm{X} \rightarrow \mathrm{Y}+\mathrm{W}$ with $\mathrm{k}_1$ as rate constant.
(ii). $\mathrm{X} \rightarrow \mathrm{Z}+\mathrm{W}$ with $k_2$ as rate constant.
The Activation energy for reaction (ii) is 3 times that of reaction (i). What is the expression for $k_1$ ?
