Chapter 12, Problem 49E

Interpretation Introduction

Interpretation: The equilibrium concentration values for the species involved in the reaction between ${\text{N}}_2$ and ${\text{H}}_{\text{2}}$ are given. The initial concentration values of the reactants 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 initial concentration values of the reactants.
