For Arrhenius Equation
\mathrm{\begin{aligned} & k=A_0 e^{\frac{-E a}{R T}} \\ & k_1=A_0 e^{-E a_1 / R T}\text {...(i) } \\ & k_2=A_0 e^{-E a_2 / R T} \text {...(ii) } \end{aligned}}

Ondiving eq (ii) by i
\mathrm{ \begin{aligned} \ln \left(\frac{k_2}{k_1}\right)=\frac{E a_1-E a_2}{R_T} & =\frac{20,000}{8.314 \times 250} \\ & =9.62 \end{aligned} }
