The results of the proposed functional form that are fitted to the experimental data are shown in Figure Figure shows that our functional form outperforms the Arrhenius equation for all reactions. Our method can accurately reproduce the experimental rate constants for the entire temperature range up to the critical temperature of the solvent while the Arrhenius equation starts to deviate from the experimental data above around 400 K. The mean absolute error (MAE) and root-mean-square error (RMSE) of each method are summarized in Table . Three different errors are computed by using (1) the entire range of temperature (All 𝑇 ), (2) temperature below 400 K (𝑇 ≤ 400 K), and (3) temperature above 400 K (400 K < 𝑇 ). It can be seen that our fitted functional form has a much lower error with a MAE/RMSE of 0.07/0.09 in log 10 𝑘 liq for the entire 𝑇 range compared to the Arrhenius equation that has a MAE/RMSE of 0.25/0.35 in log 10 𝑘 liq . Below 400 K, both the proposed functional form and the Arrhenius equation have similar fitting errors. However, at elevated temperatures above 400 K, the Arrhenius form cannot fit to the experimental data well and has a substantially higher error. Our proposed functional form, on the contrary, has a consistently low error for all temperature ranges.
