Assuming the validity of R a null's law, do the following calculations for the benzene(1) / toluene(2)

Question:

Assuming the validity of R a null's law, do the following calculations for the benzene(1) / toluene(2) system:
(а) Given x1 = 0.33 and T = 100°C. find y1 and P,
(b) Given y1 = 0.33 and T = HXFC. find x1 and P.
(f) 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 xi and y1.
(f) For pun (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 VLB model for this system at the stated tor computed) conditions?
