Abstract

Theoretical calculations of thermodynamic mixing properties viz., Gibbs’ free energy of mixing GM , heat of mixing HM , entropy of mixing SM , as well as the activity and its coeffi cients, are performed using the Bhatia–Hargrove complex formation model. The mixture is assumed to be pseudobinary. The components exhibit a negative deviation from Raoult’s behavior, and the system is weakly interacting in nature.
