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,

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

As the acetone concentration increases, the solubility curves approach each other

Both the phases become identical at a particular common point on both the solubility curves called the plait point

Mass Transfer
Plate towers are preferred to packed towers, when large temperature changes are involved, because of the reason that the

Packing may be crushed due to thermal expansion/contraction of the components of the equipments

Viscosity variation of the fluids may cause channeling/flooding

None of these

Pressure drop in the equipment will be very high
