Chapter 14, Problem 14.18QP

Interpretation Introduction

Interpretation: The equilibrium constant $\left(K_{\text{p}}\right)$ expression for the given reversible reaction is to be stated.

Concept introduction: In equilibrium the concentration of the reactant is equal to the concentration of the product.

In reversible reaction reactants give products and these attained products again react to give the reactants back in their form.

A constant that express the relation between the concentrations of the reactant with the product in the gas phase at equilibrium is termed as equilibrium constant. The equilibrium constant is represented by $K_{\text{p}}$.

To determine: The equilibrium constant $\left(K_{\text{p}}\right)$ expression for the given reversible reaction.
