Chapter 16, Problem 15ST

Interpretation Introduction

Interpretation:

The change in the rates of evaporation and condensation when the system achieves equilibrium (c) is to be stated.

Concept introduction:

The vapor pressure is defined as the pressure exerted by the molecules which enter into gaseous phase by gaining sufficient energy from the liquid surface in a closed system. The vapor pressure of the liquid depends upon the strength of the intermolecular interactions among the molecules. The vapor pressure of the liquid is less if the intermolecular forces are strong.
