N2 - The solvation Gibbs and Helmholtz energies are evaluated exactly in two model systems. One is a modification of an interstitial model for water, the second is a non ideal gas mixture within the second virial approximation. In both systems the general form of the solvation Gibbs energy of a large solute s is ΔGs* = aV s + bAs where Vs and As are the volume and surface area of the solute s. We also show that this general form is likely to hold true in any real solution.
