The topic of this study, excess thermodynamic properties of the binary mixtures, is one of the most interesting phenomena in molecular physics. These properties of mixtures provide insight into the molecular interactions between the various components and can be used for the development of molecular models describing the thermodynamic behavior of mixtures. A new equation of state (EoS) by Goharshadi, Morsali, and Abbaspour (GMA EoS) has been used to calculate the different thermodynamic and volumetric properties such as density, isobaric expansion coefficient, and isothermal compressibility of liquid mixtures. Our project is devoted to predict and reproduce the volumetric properties of various liquid mixtures such as density and excess thermodynamic functions at various temperatures, pressures, and compositions using GMA EoS.
