Table 2 Average aqueous-phase effects on the activation free energy (ΔΔGact = ΔGact,liq − ΔGact,gas) as well as three solvation effect descriptors for the O–H and C–H bond cleavages of ethylene glycol over the (111) surface facet of six transition metals at 423 K (see Table 1 for 95% confidence intervals).
