Problem 10.8: The following table is a set of VLE data for methanol(1)/water(2) at 333.15 K.
a) What is the saturation pressure of methanol at 333.15 K?
b) What is the phase of the mixture that contains 50% (by mole) methanol at 333.15 K and 40 kPa?
c) At z1 = 0.2 and 30 kPa, the system is present as two phases. What is the chemical potential of methanol and water in the vapor phase using an ideal gas reference state at 300 K and 101 kPa? Is the assumption of treating the vapor phase as an ideal gas
