please help me with this question. Thank you!

Problem 4: D19.* A distillation column is separating acetone and ethanol. The column effectively has six equilibrium stages plus a partial reboiler. Feed is a two-phase feed that is 40% liquid and 75.0mol% acetone. Feed rate is 1000.0kmol/h, and the feed stage is fourth from the top. The column is now operating at a steady state with the bottoms flow valve shut off. However, a distillate product is drawn off, and the vapor is boiled up in the reboiler. L0/D=2. Reflux is a saturated liquid. CMO can be assumed. p=1atm. Equilibrium data are in Problem 4.D7. Find the distillate composition. If one drop of liquid in the reboiler is withdrawn and analyzed, predict xB. Hints: Begin this problem by re-deriving the overall and MVC material balances on the whole column. Note that there is no bottom product. What does that imply for your balances? Next, find the feed line (its slope and intercept). Next, derive the operating lines, finding the slope and intercept of each. Finally, step off your stages to estimate " xB
