The following reaction represents the removal of ozone in the stratosphere:
2O3(g) ⇌ 3O2(g)
Calculate the equilibrium constant (KP) for the reaction. In view of the magnitude of the equilibrium constant, explain why this reaction is not considered a major cause of ozone depletion in the absence of man-made pollutants such as the nitrogen oxides and CFCs? Assume the temperature of the stratosphere to be 230°C and DG°f to be temperature independent.
