Problem 13.19

A binary system of species 1 and 2 consists of vapor and liquid phases in equilibrium at temperature T, for which $$\ln \gamma_{1}=1.8 x_{2}^{2}, \ln \gamma_{2}=1.8 x_{1}^{2}, P_{1}^{\text {sat }}=1.24$$ bar, and $$P_{2}^{\text {sat }}=40.50$$ kPa. Assuming the validity of Eq. (13.19),

(a) For what range of values of the overall mole fraction $$z_{1}$$ can this two-phase system exist with a liquid mole fraction $$x_{1}=0.65$$?

(b) What are the pressure P and vapor mole fraction $$y_{1}$$ within this range?

(c) What is the pressure and composition of the azeotrope at temperature T?
