Solvent Reorganization Contributions in Solute Transfer Thermodynamics:  Inferences from the Solvent Equation of State

Solvation enthalpies of simple solutes contain contributions from (1) solute−solvent interactions and (2) solute-induced modifications of solvent−solvent interactions (solvent reorganization). It has recently been suggested in the literature that these contributions can, under certain conditions, be estimated with additional experimental data on thermodynamic response functions of the pure solvent (coefficient of thermal expansion, isothermal compressibility) and the solute solvation volume. We analyze and discuss these conditions based on computer simulations of a series of polar and nonpolar solutes in a polar and nonpolar liquid solvent.
