Question

The excessive production of ozone (O3) gas in the lower atmosphere causes rubber to deteriorate, green plants to turn brown, and persons with respiratory disease to have difficulty breathing. The reaction describing the formation of ozone from oxygen is shown below.

3 O2(g) <==> 2 O3(g)

Calculate Grxn at 300 K for this reaction in a flask where [O2] = 1.179 x 10-2 M and [O3] = 7.973 x 10-3 M.
Assume G° = 326 kJ.

Use molarity to construct the reaction quotient, and express your answer in kJ.
