11. The following graph is the boiling-point curve of a binary liquid mixture of A & B at 101.3 kPa (1 atm). A liquid mixture with 30 mol% of A and 70 mol% of B is fed at 105 mol/min to a single-stage distillation unit operated at 97.5C and 1 atm, from which liquid and vapor are removed continuously. (a) Determine the molar composition (y) and flow rate of vapor (V) removed from the distillation unit. (b) If the feed is a saturated liquid at 1 atm, determine, (1) its temperature and relative volatility; (2) the vapor pressures of components A (PA) and B (PB), assuming Raoults law is applicable. 120 110 100 Temperature" 90 80 70 0.0 0.2 0.8 1.0 0.4 0.6 Xa ya (mol frac)
