Whether the pure air contain appreciable amount of O 3 when O 2 and O 3 are in equilibrium needs to be determined. Also, the equilibrium concentration of O 3 needs to be calculated. Concept introduction: The equilibrium constant, K c is the ratio between product of the equilibrium concentrations of the products and the product of equilibrium concentrations of all reactants. All the concentrations are raised to the power of its coefficient in the balanced equation. Equilibrium constant for a particular reaction is always same at a particular temperature. Equilibrium constant expression aA + bB ⇌ cC + dD K c = [ C ] c [ D ] d [ A ] a [ B ] b Following criteria are considered for equilibrium mixtures. If K c > 10 3 , the products predominate over reactants. Since K c is very large, the reaction proceeds nearly to completion. If K c < 10 3 , the reactants predominate over products. Since K c is very small, the reaction may not proceed to completion or may not proceed at all. If K c is between 10 − 3 − 10 3 , appreciable concentration of both reactants and products are present in the equilibrium mixture.

Solution Summary: The author explains that the equilibrium constant, K_c, is the ratio between the products and the product of equilibrium concentrations of all reactants.
Whether the pure air contain appreciable amount of O3 when O2 and O3 are in equilibrium needs to be determined. Also, the equilibrium concentration of O3 needs to be calculated.
Concept introduction:
The equilibrium constant, Kc is the ratio between product of the equilibrium concentrations of the products and the product of equilibrium concentrations of all reactants. All the concentrations are raised to the power of its coefficient in the balanced equation. Equilibrium constant for a particular reaction is always same at a particular temperature.
Equilibrium constant expression
aA + bB ⇌ cC + dDKc=[C]c[D]d[A]a[B]b
Following criteria are considered for equilibrium mixtures.
If Kc>103, the products predominate over reactants. Since Kc is very large, the reaction proceeds nearly to completion.
If Kc<103, the reactants predominate over products. Since Kc is very small, the reaction may not proceed to completion or may not proceed at all.
If Kc is between 10−3−103, appreciable concentration of both reactants and products are present in the equilibrium mixture.
