Test the liquid–vapor equilibrium data for the binary system of methanol (1)–water (2) at 40°C presented in Problem 8.53 for thermodynamic consistency by using the area test.

Problem 8.53

Liquid–vapor equilibrium data have been collected for a binary system of methanol (1)–water (2) at 40°C. Mole fraction of liquid vs. total pressure are reported in the table below. Develop a computer spreadsheet or write a program to fi nd the three-suffi x Margules parameters, A and B, that best fi t the data by doing the following:
