Work problem 11.26 using the

(a) Wilson equation

(b) NRTL equation

(c) UNIQUAC equation

Data from problem 11.26

Fit the specified model to the methanol(1) + benzene(2) system T-x-y data at 760 mmHg by minimizing the sum of squares of the pressure residual. Plot the resultant fit together with the original data for both phases (Hudson, J.W., Van Winkle, M. 1969. J. Chem. Eng. Data 14:310), using One-parameter Margules equation

Two-parameter Margules equation
