Chapter 13, Problem 121CP

Interpretation Introduction

Interpretation: The pressure at which $95\%$ of the Oxygen molecules dissociate is to be calculated.

Concept introduction: The equilibrium constant $K$ describes the ratio of the reactant to the product on the equilibrium conditions in terms of molar concentration.

The equilibrium constant depends upon temperature.

Law of mass action is applicable on the equilibrium reactions.

The Le Chatelier’s principle states that the addition of the reactants shifts the equilibrium to the right while the addition of product shifts the equilibrium to the left at constant temperature.

The dissociation of the species is denotes by the symbol $\alpha$.

To determine: The pressure at which $95\%$ of the Oxygen molecules dissociate at the constant temperature.
