Chapter 12, Problem 109CP

Interpretation Introduction

Interpretation: The decomposition reaction of a given mass of ${\text{SO}}_{\text{3}}$ is given. The total pressure and the density of the gaseous mixtures have been stated. The value of the equilibrium constant $\left(K_{\text{p}}\right)$ for the reaction 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 $\left(K_{\text{p}}\right)$

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