Question

In the mixture of liquid and vapor compositions, identify the type of component present in between the two components (at equilibrium point).

(a) Regular solution

(b) Equilibrium solution

(c) Transition solution

(d) Steady state solution

This question was addressed to me in examination.

The above asked question is from Uses and Limitations of Phase Rule in portion Phase Rule of Engineering Chemistry I

Answer 1

Correct answer is (d) Steady state solution

Easy explanation: Since phase rule cannot determine multiple phases in a single system, regular solution is not obtained. Similarly, equilibrium solution is also not obtained (according to Weiss law). Thus a steady solution is obtained.
