this is a full question , i want solution of my homwork

Question 1 One thousand kmol/h of 30mol%n-hexanejand 70%n-octane is distilled in a column consisting of a partial reboiler, one equilibrium plate, and a partial condenser, all operating at 1atm. The feed, a bubble-point liquid, is fed to the reboiler, from which a liquid bottoms is withdrawn. Bubble-point reflux from the partial condenser is returned to the plate. The vapor distillate contains 80mol hexane, and the reflux ratio, L/D, is 2. Assume the partial reboiler, plate, and partial condenser are equilibrium stages. a) Using the McCabe-Thiele method, calculate the bottoms composition and kmol/h of distillate produced. b) If is assumed to be 5 (actually, 4.3 at the reboiler and 6.0 at the condenser), calculate the bottoms composition analytically. 1. Calculate the bottoms composition again analytically, but instead of assuming relative volatility (RV)=5, use the equilibrium curve given. (Note: You're required to solve the problem analytically, so use the equilibrium curve as needed, but not the Mc Cabe Thiele Method.)
