Chapter 16, Problem 44E

Interpretation Introduction

Interpretation:

The solubility product $\left(K_{sp}\right)$ for ${\text{N}}_{\text{2}}{\text{O}}_{\text{4}}\left(g\right)\rightleftarrows {\text{2NO}}_{\text{2}}\left(g\right)$ reaction is to be calculated.

Concept introduction:

The solubility product is the ability of the solid to dissolve in aqueous solution. The more the solubility product the more the solid dissolves in solution. It is denoted as $K_{sp}$. It is known as solubility product constant. It is represented as the ratio of product concentration to reactant concentration raised to their stoichiometric coefficients as shown below.

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

It can also be represented in partial pressure form as shown below

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

Also, the concentration of liquid and solid is not considered in writing the expression.
