Three Intermolecular Potential Models
This simulation considers three models for intermolecular potentials: square-well, Suthlerand, and Lennard-Jones. Potentials for molecule A (red), and molecule B (blue), and for an A-B mixture (dashed purple) are shown. The variable λ is the square-well potential parameter. The binary interaction parameter, k, attempts to represent non-idealities in the mixture, with a value of zero for the ideal case. The attractive-strength parameter is the ratio of the attractive strength of molecule B to that of molecule A. The molecular-size parameter is the ratio of the diameter of molecule B to that of A.
