Q$1.$ A continuous, steady$-$state distillation column with a total condenser and a partial reboiler is separating methanol from water at one atmosphere. The feed rate is $100$ kg mole per hour. The feed is $55$ mole $\%$ methanol and $45$ mole $\%$ water. We desire a distillate product that is $90$ mole $\%$ methanol and a bottoms product that is $5$ mole $\%$ methanol. Assume CMO.

a$.$ Obtain and use the vapor liquid equilibrium data for methanol$-$water form any available recourse

b$.$ If the external reflux ratio L$/$D $=1\mathrm{.}25$ plot the top operating line.

C$.$ If the boilup ratio$/$B $2\mathrm{.}0$ plot the bottom operating line.

d$.$ Step off stages starting at the bottom with the partial reboiler. Use the optimum feed stage. Report the optimum feed stage and the total number of stages.

e$.$ Plot the feed line. Calculate its slope. Calculate q$.$ What type of feed is this?

please solve it carefully with showing all steps please solve it correctly i want it today
