On the partitioning of benzene between water and n-alkanes

The Gibbs energy cost of cavity creation and the Gibbs energy gain due to benzene-alkane attractive interactions depend on the chain-length of the n-alkane molecule; both these Gibbs energy contributions account for the difference in size between the solute and solvent molecules, disproving the need to correct the Ben-Naim standard transfer Gibbs energy values by a Flory-Huggins correction term.
