A batch distillation process is used to separate a mixture of ethanol and water. The mixture has an initial composition of 30% ethanol and 70% water by volume. The distillation process operates at a total pressure of 1 atm and a temperature of 78°C.

(a) Calculate the boiling point of the mixture.

(b) Calculate the relative volatility of ethanol and water.

(c) Determine the composition of the distillate and the residue at a vapor-liquid equilibrium (VLE) stage where the vapor leaving the stage is 60% ethanol.
