Ten mole pounds of an equimolar solution of ethanol and water is heated from 288.706 K to a temperature at which half of the original mixture evaporates (on a molar basis). Assume that the vapor formed remains in contact with the remaining liquid.

a) To what temperature (K) is the mixture heated?

b) What is the composition of the vapor formed?

c) How much heat is added?

Anthoine constants:

Ethanol: A=18.9119, B=3803.98, C=-41.68

Water: A=18.3036, B=3816.44, C=-45.13
