Chapter 14, Problem 14.42CP

(a)

Interpretation Introduction

Interpretation:

The balanced chemical equation for the reaction should be identified.

Concept introduction:

Equilibrium is the condition at which the rate of formation of product is equal to the rate of disappearance of reactant.
The equilibrium constant for the overall reaction can be shown as:

  $\text{K }={\left[\text{AB}\right]}^2/\left[{\text{A}}_{\text{2}}\right]{\left[\text{B}\right]}^2$

A represents red spheres

(b)

Interpretation Introduction

Interpretation:

Impact on the concentration of AB on decreasing the volume should be identified.

Concept introduction:

Equilibrium is the condition at which the rate of formation of product is equal to the rate of disappearance of reactant.
The equilibrium constant for the overall reaction can be shown as:

  $\text{K }={\left[\text{AB}\right]}^2/\left[{\text{A}}_{\text{2}}\right]{\left[\text{B}\right]}^2$

A represents red spheres.
