Chapter 14, Problem 14.144CP

Interpretation Introduction

Interpretation:

Use the initial concentrations of each species and first calculate the reaction quotient to decide which side the equilibrium will shift to. Once known, calculate the equilibrium concentrations using the equilibrium constant and initial concentrations.

Concept introduction:

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

To classify:

The equilibrium concentrations of each species.
