d.) Basing calculations on the Modified Raoult's Law, find parameters for the margules Equation that provide the best fit of GE/RT to the data and prepare a Pxy Diagram that compares the experimental points with curves determined from the correlation.
e.) Repeat part (c) for the van Laar Equation.
f.) Repeat part (c) for the Wilson Equation.

I reviewing concepts and I don't understand how the summation of chemical potentials with respect to one another is equal to zero in phase equilibria or how the first two terms in the expression for total gibb's energy looked generalized to be applicable to both phases.
Thumbtack,
Please look at my answers to your questions on the post where I entertain questions for test 2.
where the answer?
