A binary system of species l and 2 consists of vapor and liquid phase* in equilibrium at

Question:

A binary system of species l and 2 consists of vapor and liquid phase* in equilibrium at temperature T. The overall mole fraction of species I in the sy stem is d = 0.65.
At temperature T.
• In γ1 = 0.67x22 In y2 = 0.67 x21.
• P1sat = 32.27 kPa P2sat = 73.14 kPa.
Assuming the validity of Eq. (10.5).
(a) Over what range of pressures can this system exist as two phases al given T and z1?
(b) For a liquid-phase mole fraction x1 = 0.75, what is the pressure P and what molar fraction V of the system is vapor?
(c) Show whether or not the system exhibits an azeotrope.
