11-23. You are interested in evaluating how well you can
predict the phase-behavior of a system using an
excess molar Gibbs free energy model. Here, use
the van Laar predictions (from the VDW-defined
parameters) relative to fitting the data (in Table
P11-23) with the van Laar model for the methanol
(1) + water (2) system at 328.15 K. What is your
conclusion based on these results?

methanol (1) + water (2) at 328.15 K.
