Chapter 13, Problem 7STP

Interpretation Introduction

Interpretation:

It is to be explained whether the given statement is correct or not.

Concept Introduction :

A liquid's evaporation rate can be determined by looking at the equilibrium vapor pressure. It has to do with how often particles tend to float away from liquids (or a solid).

Answer to Problem 7STP

The statement and the reason both are correct.

Explanation of Solution

When the forward and reverse processes move ahead and backward at the same rate, with no discernible change in the system, this is referred to as dynamic equilibrium for reversible processes. The concentrations or partial pressures of all the species participating in the process stay constant once dynamic equilibrium has been reached.

In an open system, a dynamic equilibrium exists in which the rates of evaporation and condensation are equal. Thus, the given statement is correct, and the reason given is also correct.
