Abstract
The hard‐sphere model for fluids has been applied by Snider and Herrington to the calculation of the excess thermodynamic functions of binary liquid mixtures and also to the problem of the solubility of gases in liquids. While remarkably successful in the first case, it appeared to fail rather badly when applied to gas solubility. It is shown that this apparent failure was due to Snider and Herrington's choice of experimental data, and that in fact the approach is much more effective than they concluded in correlating and predicting the thermodynamic parameters for solutions of gases in low‐boiling liquids. Results of calculations are presented for the systems argon–neon, nitrogen–hydrogen, methane–helium, and hydrogen–helium, where the first named component is the liquid solvent.
