Chapter 12, Problem 55E

Interpretation Introduction

Interpretation: The equilibrium constant $\left(K_{\text{p}}\right)$ value for the reaction between ${\text{SO}}_{\text{2}}$ and ${\text{O}}_{\text{2}}$ is given. The initial partial pressure values for the species involved are also given. The equilibrium partial pressures of the species involved are 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 $K_{\text{p}}$.

To determine: The equilibrium partial pressures of the species involved.
