Application of hard sphere equation of states for the calculation of thermodynamic properties of liquids

Different models for the Hard Sphere equation of states have been utilized to compute the two thermodynamic properties, isothermal compressibility (βT) and the thermal expansion coefficient (αP) . The pure liquids used for investigation are n-hexane, n-heptane, n- dodecane, cyclohexane and toluene. Both the properties have been calculated at varying temperatures (293.15K to 333.15K). The obtained values of isothermal compressibility and thermal expansion coefficient have been compared with the experimentally evaluated values. The results of the calculation are observed to be in satisfactory agreement with experimental findings collected from literature.
