Question

Which of the following are not vapor liquid phase diagrams?

(a) Boiling point diagrams

(b) Txy, Pxy diagrams

(c) Ternary diagrams

(d) Freezing point diagrams

This question was posed to me in unit test.

This question is from Gas Liquid Equilibrium topic in portion Contact Equilibrium Separation Process of Food Processing Unit Operations

Answer 1

The correct option is (d) Freezing point diagrams

Explanation: Boiling point diagrams, Txy, Pxy diagrams, ternary diagrams and solubility diagrams are the vapor liquid phase diagrams. These diagrams signify a binary mix and all the compositions are expressed as mole fractions of the more volatile component.
