Chapter 13, Problem 62E

Interpretation Introduction

Interpretation:

The total pressure for the decomposition reaction of ammonium chloride $\left[{\text{NH}}_{\text{4}}{\text{Cl}}_{\left(\text{s}\right)}\right]$ is given.  The value of equilibrium constant is to be calculated.

Concept introduction:

The state when the reactants involved in a chemical reaction and the products formed in the reaction exist in concentrations having no further tendency to change is known as an equilibrium state of the reaction.  When the equilibrium constant is expressed in terms of pressure, it is represented as $K_{\text{p}}$.
