Question

11-21. Consider the experimental data in Table P11-21 for the ethyl acetate (1) + cyclohexane (2)system at 293.15k Please fit this system to the 2-pаrameter Mаrgules equation and plot the

Pxy curve for the system (along with the experimental data and Raoult Law predictions). Also, plot the natural logarithm of activity co-efficients and the excess molar Gibbs free energy (divided by RT) both on the same curve.
