โฆ Synopsis
A chemical-physical model of solution behavior is developed to represent liquid activities in compound-forming binary nonelectrolyte systems as a function of both composition and temperature. It uses complex formation from solvation reactions for the chemical contribution, and regular solution theory for physical interactions. The technique is applied successfully to the prediction of solid-liquid phase equilibria.

Phase equilibrium data have been obtained for the binary systems nitrogen-argon and nitrogen-carbon monoxide at 8332ยฐK. and for the systems nitrogen-methone, argon-methane, and carbon monoxide-methane at 90.67"K. Total pressures and compositions of both phases were measured. Parameters have been cal
