1. Consider a feed containing benzene, toluene, and cumene with mole fractions of 0.25, 0.5, and 0.25, respectively. The relative volatilities of these components with respect to toluene is 2.25, 1,and 0.21. If the fractional recovery of benzene in the distillate is 0.9 and that of toluene in the bottoms is 0.9, solve for the component flow rates in the bottoms and distillate using the Fenske equation. Assume that the feed flow rate is 100 kmol/hr.

2. Assume that the feed in Problem 1 is saturated liquid. What is the minimum reflux ratio? Use the Underwood equation and toluene as the reference component.

A mixture of benzene and toluene is in equilibrium with its vapor at 50oC. What mole fraction of benzene is in the vapor phase? You may assume that this system follows Raoult's Law. Note: when solving Antoine's equation it is best to keep all sig figs through calculation and then truncate them at the end. Question options: 0.687, 0.807, 0.572, 0.614, 0.746, 0.913

a stream consisting of 44.6 mole% benzene and 55.4% toluene is fed at a constant rate to a process unit that produces two product streams, one a vapor and the other a liquid. The vapor flow rate is initially zero and asymptotically approaches half of the molar flow rate of the feed stream. Throughout this entire period, no material accumulates in the unit. When the vapor flow rate has become constant, the liquid is analyzed and found to be 28.0...
