Chapter 7, Problem 7.30P

Interpretation Introduction

Interpretation:

Equilibrium expression should be written for the given reaction ${\text{HNO}}_{\text{3}}{\text{(aq)+H}}_{\text{2}}\text{O(l)}◰\; \hspace{1em}{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}{\text{(aq)+NO}}_{\text{3}}{}^{\text{-}}\text{(aq)}$

Concept Introduction:

Equilibrium constant may be defined as the ratio of concentrations of products to that of reactants.

Thus ${\text{K}}_{\text{eq}}\text{=}\frac{\text{[Products]}}{\text{[Reactants]}}$.
