Question

What will happen if the rate of evaporation is equal to the rate of condensation in the water?

(a) solid-liquid equilibrium

(b) liquid-vapor equilibrium

(c) solid-vapor equilibrium

(d) melting

This question was addressed to me in homework.

I want to ask this question from Equilibrium in Physical Processes in chapter Equilibrium of Chemistry – Class 11

Answer 1

Correct choice is (b) liquid-vapor equilibrium

For explanation I would say: When the rate of evaporation is equal to the rate of condensation water in the liquid phase and steam in vapor phase remained at equilibrium because its forward rate of the reaction and the backward rate of the reaction is the same at this particular temperature.
