Chapter 16, Problem 27E

Interpretation Introduction

Interpretation:

The ionization constant for nitrous acid is to be stated.

Concept introduction:

In a chemical reaction, when the rates of both forward and reverse reaction are equal then the chemical reaction is said to be at equilibrium. They are reversible in nature. Equilibrium constant is denoted as $K_{eq}$. Mathematically, it is represented as the ratio of product concentration to reactant concentration raised to their stoichiometric coefficients,

$K_{eq}=\frac{{\left[\text{Product}\text{concentration}\right]}^{\text{a}}}{{\left[\text{Reactant}\text{concentration}\right]}^{\text{b}}}$
