#2 From the data given in the following table, construct a complete temperature-composition diagram for the system ethanol-ethyl acetate for 1.013 bar. A solution containing 0.8 mole fraction of ethanol, EtOH, is distilled completely at 1.013 bar. (a) What is the composition of the first vapor to come off, and (b) what is that of the last drop of liquid to evaporate? (c) What would be the values of these quantities if the distillation were carried out in a cylinder provided with a piston so that none of the vapor could escape?

From the data given in the following table, construct
a complete temperature-composition diagram for the system
ethanol-ethyl acetate for 1.013 bar. A solution containing 0.8
mole fraction of ethanol, EtOH, is distilled completely at 1.013
bar. (a) What is the composition of the first vapor to come off,
and (b) what is that of the last drop of liquid to evaporate? (c)
What would be the values of these quantities if the distillation
were carried out in a cylinder provided with a piston so that none
of the vapor could escape?
