Chapter 12.2, Problem 12.4E

(a)

Interpretation Introduction

Interpretation:

Equilibrium constant ${\text{K}}_{\text{c}}$ for given reaction has to be calculated.

    $\frac{3}{2}{\text{O}}_{\text{2(g)}}\underset{}{\rightleftharpoons }{\text{O}}_{\text{3(g)}}$

Concept introduction:

Equilibrium constant: At equilibrium the ratio of products to reactants (each raised to the power corresponding to its stoichiometric coefficient) has a constant value, K

  For a general reaction, $\text{aA+bB}\rightleftarrows \text{cC+dD}$

  $\text{Equilibrium}\text{constant}\text{K}\text{=}\frac{{\left[\text{C}\right]}^{\text{c}}{\left[\text{D}\right]}^{\text{d}}}{{\left[\text{A}\right]}^{\text{a}}{\left[\text{B}\right]}^{\text{b}}}$

(b)

Interpretation Introduction

Interpretation:

Equilibrium constant ${\text{K}}_{\text{c}}$ for given reaction has to be calculated.

    ${\text{2O}}_{\text{3(g)}}\underset{}{\rightleftharpoons }{\text{3O}}_{\text{2(g)}}$
