Assuming the validity of Raoult's law, do the following calculations for the benzene(1) / toluene(2) system:
(a) Given x1 = 0.33 and T = 100°C, find y1 and P.
(b) Given y1 = 0.33 and T = 100°C, find x1 and P.
(c) Given x1 = 0.33 and P = 120 kPa, find y1 and T.
(d) Given y1 = 0.33 and P = 120 kPa, find x1 and T.
(e) Given T = 105°C and P = 120 kPa, find x1 and y1.
(f) For part (e), if the overall mole fraction of benzene is z1 = 0.33, what molar fraction of the two-phase system is vapor?
(g) Why is Raoult's law likely to be an excellent VLE model for this system at the stated (or computed) conditions?
