Mass Transfer
When acetone is added in a two layer mixture of methyl isobutyl ketone and water at 30°C, the acetone distributes between the two layers and the composition of the layer follows two solubility curves. For this system,

Both the phases become identical at a particular common point on both the solubility curves called the plait point
As the acetone concentration increases, the solubility curves approach each other
All of these
The distribution curve which is a plot between x (acetone concentration in one phase) and y (acetone concentration in other phase) is analogous to x-y curve used in distillation and absorption termina

Mass Transfer
In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because

Temperature is less
Saturated steam is used for steam distillation
Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition
Total pressure is less
