Chapter 12, Problem 51E

Interpretation Introduction

Interpretation: The value of the equilibrium constant for the reaction between ${\text{SO}}_2$ and ${\text{NO}}_{\text{2}}$ is given. The equilibrium concentrations of the four gases involved in the system 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 concentration, it is represented as $K$.

To determine: The equilibrium concentrations of the four gases involved in the system.
