2. (3 pts) A binary system of species 1 and 2 consists of vapor and liquid phases in equilibrium at : 0.65. At temperature = temperature T. The overall mole fraction of species 1 in the system is Z T, we know: In y = 0.67x2 In y2 = 0.67x psat = 32.27 kPa Psat = 73.14 kPa Assuming the validity of Modified Raoult's Law: A.) Over what range of pressures can this system exist as two phases at the given T and z? Hint: This pressure range is from the dewpoint to the bubblepoint for the two phases. B.) For a liquid-phase mole fraction x = 0.75, what is the pressure P and what molar fraction V of the system is vapor
