Question: In a binary distillation process,the molar latent heat of one of the components is half that of the other.Employing two film theory concepts,obtain an expression for the ratio of transfer of one of the components in the vapor phase to that which would be obtained had the molar latent heats of both components been equal.
What is the value of this ratio when the mole fraction of one of its components is 0.7 at the liquid/vapor interface and 0.3 in the bulk of the vapor at a given point in the column.  Edit
