Flory's statistical theory has been extended for the computation of internal pressure, isentropic compressibility, isothermal compressibility and Pseudo Gruneisen parameter of binary mixture nitrobenzene+benzene at pressure up to 10 MPa and at two different temperatures (293.15K, 303.15K & 313.15K). For a comparative study of the isothermal compressibility of this system, equation of state based on the psuedo spinodal hypothesis developed by Baonza et al has also been utilized to deduce the isothermal compressibility of this mixture. The computed values of Pint, βT, βs and Γ have been compared with the experimental findings available in literature. Satisfactory agreement has been found between experimental and theoretical values.

Abstract


Flory's statistical theory has been extended for the computation of internal pressure, isentropic compressibility, isothermal compressibility and Pseudo Gruneisen parameter of binary mixture nitrobenzene+benzene at pressure up to 10 MPa and at two different temperatures (293.15K, 303.15K & 313.15K). For a comparative study of the isothermal compressibility of this system, equation of state based on the psuedo spinodal hypothesis developed by Baonza et al has also been utilized to deduce the isothermal compressibility of this mixture. The computed values of Pint, βT, βs and Γ have been compared with the experimental findings available in literature. Satisfactory agreement has been found between experimental and theoretical values.
