Chapter 6, Problem 6.73P

Interpretation Introduction

(a)

Interpretation:

Chemical equation for the given equilibrium constant should be written.

  $\text{K = }\frac{\left[{\text{A}}_{\text{2}}\right]}{{\left[\text{A}\right]}^{\text{2}}}$

Concept Introduction:

The net concentrations of the reactants and products do not change at equilibrium. They are used to define an expression and the equilibrium constant (K) which has a characteristic value.

For a reaction at a given temperature,

  $\text{K=}\frac{\left[\text{Products}\right]}{\left[\text{reactants}\right]}$
