The Arrhenius equation for two first order equations:

$\mathrm{A}⟶\mathrm{B}$ and $\mathrm{C}⟶\mathrm{D}$ is given by

$k_1={10}^{16}{\mathrm{e}}^{-79.9(\mathrm{Kcal}//\mathrm{RT}};{\mathrm{k}}_2={10}^{12}{\mathrm{e}}^{-43.1\text{ (Kcal }/\mathrm{RT}}$

Calculate the temperature (Kelvin) at which k1 becomes equal to ${\mathrm{K}}_2$. Given : In 2 = 2.3 [Express your answer by dividing it by 1000.)
