Chapter 14, Problem 14.156MP

Interpretation Introduction

Interpretation:

Determine the amount of O₃ molecules that are present at equilibrium under the given conditions. We will determine the moles of O₃ and use Avogadro’s number to determine the number of molecules.

Concept introduction:

• Le Chatelier’s principle states that any system in equilibrium that is subject to change in concentration, temperature, volume or pressure, the system will adjust itself to account for the changes and will reach a new equilibrium.
• The equilibrium constant for gaseous species is K_pand is the ratio of the partial pressures of products and reactants.
• The equilibrium constant using concentrations of species is K_cand is the ratio of the concentrations of products and reactants.

To classify:

The number of O₃ molecules present at equilibrium.
