Molecular thermodynamics on the basis of an equation of state for argon. III. Systems of appreciably nonspherical linear molecules

Abstract A molecular model based on an equation of state for pure argon is applied to various systems involving appreciably nonspherical molecules. Since the pure components are not described adequately, their potential parameters are fitted at each temperature separately to ensure the proper vapor pressures and liquid volumes. Used in this way, the model makes reasonable predictions of the thermodynamic behavior of the binary mixtures considered. Again, the introduction of a binary parameter in the dispersion potential does not lead to any significant overall improvement.
