10.16. A binary system of species 1 and 2 consists of vapor and liquid phases in equilibrium at temperature T. The overall mole fraction of species 1 in the system is z₁ = 0.65. At temperature T. • Inyi = 0.67x² • P= 32.27 kPa In y2 = 0.67x7. P₂ = 73.14 kPa. Assuming the validity of Eq. (10.5), (a) Over what range of pressures can this system exist as two phases at given 7 and 21? (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.

10.16. A binary system of species 1 and 2 consists of vapor and liquid phases in equilibrium at temperature T. The overall mole fraction of species 1 in the system is z₁ = 0.65. At temperature T. • Inyi = 0.67x² • P=32.27 kPa In y2 = 0.67x7. Pat = 73.14 kPa. Assuming the validity of Eq. (10.5), (a) Over what range of pressures can this system exist as two phases at given 7 and 21? (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.
