Chapter 5, Problem 5.97AP

(a)

Interpretation Introduction

Interpretation:

The direction of the equilibrium shift when the concentration of Ozone is decreased has to be given.

Concept introduction:

Le-Chatelier Principle:

If a chemical system at equilibrium is disturbed the system will react in the direction that counteracts the disturbance the stress.

Example:

  ${\text{CO}}_{\left(\text{g}\right)}{\text{+H}}_{\text{2}}{\text{O}}_{\left(\text{l}\right)}\rightleftarrows {\text{CO}}_{\text{2}}{}_{\left(\text{g}\right)}{\text{+H}}_{\text{2}\left(\text{g}\right)}$

If the concentration of the reactant is increased the equilibrium of the reaction shifted to the right side.

If the concentration of the reactant is decreased the equilibrium of the reaction shifted to the left side.
