(d)Data below shows Industrial Distillation of Methylene Chloride (MVC) and Ethylene Chloride You are required to plot the McCabe –Thiele diagram for the column showing equilibrium data for methylene chloride (MVC) and ethylene chloride, 45o line and also data for operating lines (Enriching and Stripping sections of the distillation column) all on the same plot. From the diagram determine the optimal feed stagefor the column

please help me with these, advance thank you. :D
