Question

3. Please refer to the VLE data in Problem 2 for the Ethanol (1)/Cyclohexane (2) at 293.15 °K when addressing Problem 3. a. At the azeotrope, please determine zi, z2, x1, x2, yı, and y2. b. At the liquid phase composition of the azeotrope, please model the system asan Ideal Vapor over an Ideal Liquid. Please determine the value of P in kPa. c. At the liquid phase composition of the azeotrope, please determine the percent error in the pressure if we model the system as Ideal/Ideal. d. Please model the system as an Ideal Vapor over a Real Liquid. At the liquid phase composition of the azeotrope, please determine the value of y₁ and Y2 inappropriate units. e. At the liquid phase composition of the azeotrope please determine the partial pressures (P1 and P2) of each species in kPa.
