A liquid containing 60 mol% toluene (Tb = 110 °C) and 40 mol% benzene (Tb = 80 °C) is continuously distilled in a single-equilibrium-stage unit at atmospheric pressure. What percentage of benzene in the feed leaves in the vapour if 90% of the toluene entering in the feed leaves in the liquid. Assume a relative volatility of 2.3 and obtain the solution graphically. The solution may require an iterate approach.

A liquid mixture of benzene and toluene is contained in a closed vessel at 60°C. The only other component in the system is nitrogen gas which is used to pressurize the system to 1 atm total pressure (absolute). The liquid is 70 mole% benzene and 30 mole% toluene, and the N2 is considered non-condensable (i.e., the liquid mole fraction of nitrogen is zero). Consider the mixture to be ideal, and determine the vapor mole fractions of the three components. (Document...

A mixture of 20.0 mol% benzene, 5.00 mol% toluene, and 75.0 mol% air is compressed isothermally at 70 degrees C until condensation first appears. What is the mole fraction of benzene in the condensate? You may assume that air is noncondensable (and thus its vapor pressure is large) and this system obeys 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: 0.605, 0.832,...
