5. (20%) Vapor-liquid equilibrium data for mixtures of benzene and toluene at 1 atm is given in the following Txy diagram: Temperature (°C) 115 110 105 100 95 90 85 80 75 70 65 0? 0.2 Vapor Liquid 0.8 1.0 0.4 0.5 0.6 Mole fraction benzene P = 1 atm ? (a) Using the Txy diagram, determine the bubble point temperature and the equilibrium vapor composition associated with a 50 mole% benzene - 50 mole% toluene liquid mixture at 1 atm. If the mixture is steadily vaporized until the ? remaining liquid contains 30% benzene, what is the final temperature. (b) Using the Txy diagram, determine the dew point temperature and the equilibrium liquid composition associated with a mixture of benzene and toluene vapors containing 50 mole% benzene at 1 atm. If condensation proceeds until the remaining vapor contains 70% benzene, what is the final temperature? (c) Use Raoult's law to estimate the bubble-point temperature and vapor composition in equilibrium with a liquid mixture containing 30.0 mole% benzene
