Chapter 12, Problem 47E

Interpretation Introduction

Interpretation:  A $3.0\text{L}$ rigid container filled with $12.0\text{moles}$ of gaseous ${\text{SO}}_3$ is given. The reaction that takes place is stated. The value of the 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 concentration, it is represented as $K$.

To determine: The equilibrium constant $\left(K\right)$ for the given reaction.
