Chapter 12, Problem 108CP

(a)

Interpretation Introduction

Interpretation: For the given decomposition equilibrium reaction if the volume increased by a factor of 10 then the effect on mole percent is to be stated and explained. The decomposed mole percent of ${\text{N}}_{\text{2}}{\text{O}}_{\text{5}}$ at equilibrium 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.

To determine: The effect on mole percent of ${\text{N}}_{\text{2}}{\text{O}}_{\text{5}}$ if volume is increased by a factor of 10.
