Question

Does Arrhenius constant change with temperature?

Answer 1

The Arrhenius equation for the rate constant is given as;

$$\begin{gathered} \mathrm{k}={\mathrm{Ae}}^{-\left(\raisebox{1ex}{$\mathrm{Ea}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{RT}$}\right.\right)} \\ \mathrm{Here}, \\ \mathrm{k}\mathrm{is}\mathrm{the}\mathrm{rate}\mathrm{constant} \\ \mathrm{A}\mathrm{is}\mathrm{the}\mathrm{pre}-\mathrm{exponential}\mathrm{factor} \\ {\mathrm{E}}_{\mathrm{a}}\mathrm{is}\mathrm{the}\mathrm{activation}\mathrm{energy} \\ \mathrm{R}\mathrm{is}\mathrm{the}\mathrm{universal}\mathrm{gas}\mathrm{constant} \\ \mathrm{T}\mathrm{is}\mathrm{the}\mathrm{absolute}\mathrm{temparature} \end{gathered}$$

The rate of the constant increases with an increase in the temperature.
