From Figure , it can be seen that the reactions mostly exhibit the Arrhenius behavior at moderate temperatures and show a rapid decrease or increase in rate constants above approximately 450 K. The reactions have different shapes of curves for the log 10 𝑘 vs 1000∕𝑇 plots, and the results indicate that our method is able to replicate all of these different Thus, it is possible that the relatively poor performance of our method on Reaction 4 is due to its high experimental uncertainty.
