A solution of water(1) and methanol(2) with X1=0.3120 has a total vapor pressure of 211.3 Torr. Y,=0.1090 in the vapor above the solution. At the temperature of these measurements, the vapor pressure of pure water is 55.03 Torr and the vapor pressure of pure methanol is 255.6 Torr. Compute the activity and activity coefficients for each component in the solution. While you should NOT assume that the solution is ideal, you should use definitions from the ideal solution model as the basis for these calculations.

Question
A solution of water (1) and methanol (2) with \( X_1 = 0.3120 \) has a total vapor pressure of 211.3 Torr. \( Y_1 = 0.1090 \) in the vapor above the solution. At the temperature of these measurements, the vapor pressure of pure water is 55.03 Torr and the vapor pressure of pure methanol is 255.6 Torr. Compute the activity and activity coefficients for each component in the solution. While you should NOT assume that the solution is ideal, you should use definitions from the ideal solution model as the basis for these calculations.
