HW3 Differential Distillation of Benzene-Toluene. A mixture containing 70 mol % benzene and 30 mol % toluene is distilled under differential conditions at 101.32 kPa (1 atm). A total of one third of the moles in the feed is vaporized. Calculate the average composition of the distillate and the composition of the remaining liquid. Use equilibrium data in Table 11.1-1. given as mole fraction n-heptane. 0.284 0.097 0.067 0.459 0.184 0.131 0.039 0.012 0.078 0.025
Problem 4.40 Sequential Distillation A liquid mixture containing 30.0 mole% benzene (B), 25.0% toluene (T), and the balance xylene (X) is fed to a distillation column. The bottoms product contains 98.0 mole% X and no B, and 85.5% of the X in the feed is recovered in this stream. The overhead product is fed to a second column. The overhead product from the second column contains 91.0% of the B in the feed to this column. The composition of this...
A mixture of chloroform and acetone has a vapour pressure of 311 Torr. Calculate the mole fraction of acetone in the mixture. The vapour pressures of chloroform and acetone are 295 Torr and 332 Torr, respectively. Assume ideal behaviour.

Mole fraction of O2 = 571 Correct The mole fraction is the ratio of the number of moles of a given component in a mixture to the total number of moles in the mixture. The mole fractions can be represented in terms of pressures The total pressure PTOTAL = 0.180 atm +0.240 atm = 0.420 atm The mole fraction of CH4 in the mixture PCH 0.180 atm 0.420 atm = 0.429 PTOTAL Since it is the mixture of two gases,...
