Consider an ethanol(1) + water(2) system with 20 mol%ethanol(1) solution in water(2) at 85C. Given the followinginformation at 78.15C: gamma_1_inf = 1.6931; gamma_2_inf = 1.9523.Fit the two-parameter Margules model and estimate the total pressure (bar) of vapor in equilibrium with the liquid. Use the following Antoine constants (P in mmHg and T in C). The Antoine spreadsheet may be used to calculate the vapor pressure:
