The rate constant of two reactions as temperature $T$ are $k_{1}(T)$ and $k_{2}(T)$ and the corresponding activation energies are $E_{1}$ and $E_{2}$ with $E_{2}>E_{1}$. When temperature is raised from $T_{1}$ and $T_{2}$, which one of the following relations is correct?
(a)$\frac{k_{1}(T_{2})}{k_{1}(T_{1})}=\frac{k_{2}(T_{2})}{k_{2}(T_{1})}$
(b)$\frac{k_{1}(T_{2})}{k_{1}(T_{1})}>\frac{k_{2}(T_{2})}{k_{2}(T_{1})}$
(c)$\frac{k_{1}(T_{2})}{k_{1}(T_{1})}\geq\frac{k_{2}(T_{2})}{k_{2}(T_{1})}$
(d)$\frac{k_{1}(T_{2})}{k_{1}(T_{1})}<\frac{k_{2}(T_{2})}{k_{2}(T_{1})}$
