Consider the following T- xy diagram of ethanol(1)/toluene(2) and 1 atm. a) b) Identify the normal boiling point of species 1 and 2 as Tb,1 and Tb,2, respectively. A liquid mixture of 20-mol-% ethanol at 80 C is heated at constant pressure up to 110 C. Draw the path traced by this process, label liquid and vapor phases as V and L, respectively. c) [2 pts] Take the vapor in equilibrium with the liquid mixture with x = 0.2, and condense this vapor to its bubble point at the constant pressure of 1 atm. What is the temperature? What is the liquid phase composition at the bubble point? Indicate them on the plot as T and x, respectively. T/C 110 100 90 80 0 0.5 XI, YI 1.0
