Chapter 14, Problem 14.139CP

Interpretation Introduction

Interpretation:

Use the equilibrium constant K_cto find K_pand use that value to find the equilibrium partial pressures of the system. The total pressure can be determined from the summation of the individual partial pressures at equilibrium.

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, whichis also the ratio of the partial pressures of products and reactants.
• The equilibrium constant using concentrations of species is K_c, whichis also the ratio of the concentrations of products and reactants.

To classify:

The total pressure of the system at equilibrium.
