The Arrhenius equation for two first order equation \( \mathrm{A} \longrightarrow \mathrm{B} \) and \( \mathrm{C} \longrightarrow \mathrm{D} \) is given by \( \mathrm{k}_{1}=10^{12} \mathrm{e}^{-81.28(\mathrm{~kJ}) / \mathrm{RT}} ; \quad \mathrm{k}_{2}=10^{11} \mathrm{e}^{-43.10(\mathrm{~kJ}) / \mathrm{RT}} \)
\( P \)
At what temperature \( \mathrm{k}_{1} \) becomes equal to \( \mathrm{k}_{2} \). The unit of activation energy is \( \mathrm{kJ} / \mathrm{mol} \)
W
Use: \( \ln 10=2.3 \) and \( \mathrm{R}=8.3 \mathrm{~J} / \mathrm{K} / \mathrm{mol} \)
