The vapor pressures of benzene and toluene can be modeled by the expressions 3856.6 K T In In benzene 1 bar (² (Ptoluene 1 bar = 10.931 :-). = 11.777 4514.6 K T between the temperatures of 353 and 385 K, where the pressure is given in bars and T in K. Assuming that benzene and toluene form an ideal solution in all proportions, construct a temperature composition diagram of this system at an ambient pressure of 775 torr. (Note that 760 torr = 1 atm.) (a) Report the mole fraction of benzene in the liquid and vapor phases at T = 375 K. (b) Report the mole fraction of toluene the liquid and vapor phases at T = 360 K. You should include a copy of your diagram with your submitted work on the problem set.
