Using the data from problem 11.27, fit the specified model equation and then plot the P-x-y diagram at 80°C using the

(a) Wilson equation

(b) NRTL equation

(c) UNIQUAC equation

Data from problem 11.27

VLE data for the system carbon tetrachloride(1) and 1,2-dichloroethane(2) are given below at 760 mmHg, as taken from the literature.

Fit the data to the one-parameter Margules equation.

Fit the data to the two-parameter Margules equation.

Plot the P-x-y diagram at 80°C, based on one of the fits from (a) or (b).
