Although the method by Chung et al. evaluates the temperature-dependent solvation free energy at a solvent's saturation pressure, they showed that the method could also provide a reasonable prediction for a range of pressures as long as the temperature is not too close to the critical temperature of the solvent (i.e. T < 0.8T c ). They indicated that the pressure effect becomes more pronounced at elevated temperatures and that the method should be used for pressures close to the saturation pressure in the high temperature region (i.e. P < 1.3P sat for 0.8T c < T < T c ). Hence our method using Eq. 11 is expected to be valid for similar conditions.
