Chapter 18, Problem 47E

Interpretation Introduction

Interpretation:

The equilibrium constant expression for the equilibrium equation, ${\text{HNO}}_2\left(\text{aq}\right)+{\text{H}}_{\text{2}}\text{O}\left(\mathcal{l}\right)\rightleftharpoons {\text{H}}_{\text{3}}{\text{O}}^{+}\left(\text{aq}\right)+{\text{NO}}_{\text{2}}{}^{-}\left(\text{aq}\right)$ has to be stated.

Concept introduction:

Equilibrium constant is a constant at any point of equilibrium; where, the ratio of the concentration of the products, each raised to power of their respective coefficient, to the concentration of the reactants, each raised to a power of their respective coefficient. Equilibrium constant depends only on temperature.
