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=0.60 at temperature T. In y1 = 0.85x3 In y2 = 0.85x? Psat = 42.3 kPa Pşat = 79.7 kP Assuming the validity of the modified Raoult's Law, (a) Determine the range of pressure that this system can exist as two phases at given T and Z1. (b) For liquid mole fraction x1 = 0.47, find the pressure P and the molar fraction V of the system that is vapor. (c) Show whether or not the system exhibits an azeotrope. If an azeotrope is formed, find the azeotropic composition and pressure.

Question
Transcribed Image Text: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=0.60 at temperature
T.
In y1 = 0.85x3
In y2 = 0.85x?
Pfat = 42.3 kPa
Psat = 79.7 kP
Assuming the validity of the modified Raoult's Law,
(a) Determine the range of pressure that this system can exist as two phases at given T and
Z1.
(b) For liquid mole fraction x1 = 0.47, find the pressure P and the molar fraction V of the system
that is vapor.
(c) Show whether or not the system exhibits an azeotrope. If an azeotrope is formed, find the
azeotropic composition and pressure.
