Since linear correlations (i.e. Brønsted-Evans-Pokanyi [BEP] relationship) were observed in both activation energies (∆G † ) and the deviations of activation energy (∆∆G † ) with respect to ∆H r (Fig. ), additional linear corrections on the activation energies were made for the other 23 model reactions. Based on the similarity of intercepts and slopes, those model reactions can be classified into 9 groups (Fig. , group 4 is further divided into three subgroups, Fig. ). After applying the corresponding linear corrections, the MAE for all model reactions except three are less than 1 kcal/mol (Fig. ). However, the MAE of these three model reactions, MR 19, MR 31, and MR 40, are also close to the 1 kcal/mol target, with values of 1.05, 1.05, and 1.23 kcal/mol, respectively (detailed corrections are provided in Fig. ).
