Thermodynamics help! 9. [20 points) When combined at 300K Acetone (A) and Benzene (B) behave as an ideal solution (e.g., the mixture obeys Raoult's Law). Given PA* = 250 Torr and P8* = 100 Torr, answer the following questions: (a) Pressure is reduced on the liquid mixture until the first vapor appears. If the vapor contains 75% Benzene, what is the total pressure at this point and what is the composition of the liquid phase (e.g., XA and XB)? (b)...
