Use the UNIFAC model to predict the VLE behavior of the n-pentane(1) + acetone(2) system at 1 bar and compare to the experimental data in problem 11.11.

Data from problem 11.11:

Fit the Margules two-parameter equation to the n-pentane(1) + acetone(2) system P-x-y data below at 1 bar (Lo et al. 1962. J. Chem. Eng. Data 7:32) by fitting to x₁ = 0.503. Plot the resultant fit together with the original data for both phases. 

Compare the data with the predictions of the MAB model.
