Enthalpy of mixing of liquid hydrogen chloride and liquid xenon. Comparison of experiment and theory

Abstract

Calorimetric measurements are reported for the enthalpy of mixing H^E of liquid hydrogen chloride and liquid xenon at 182.32 K. These results are compared with values calculated from perturbation theory, using two slightly different sets of intermolecular potential models for the Xe + HCl system. Although these models give good results for the excess Gibbs energy G^E and excess volume V^E, they are found to give values that are too high for H^E.
