Correspondling states correlations for liquid compressibility and partial molal volumes of gases at infinite dilution in liquids

Abstract

Abstract A statistical mechanical solution theory is used as the basis for corresponding states formulations. Universal functions relate the compressibility to the reduced density and the partial molar volume to reduced solvent density only. Correlations are in good agreement with data for all types of nonelectrolytes over wide ranges of temperatures including saturated and compressed systems. The correlations provide simple methods for describing the isothermal pressure dependence of liquid volumes and the pressure dependence of the ideal‐solution solubility of gases in liquids.
