Solution: As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction:2NO2(g) ⥫⥬ N2(g) + 2O2(g)             K c = ?Use the following data to find the unknown

Problem

As an EPA scientist studying catalytic converters and urban smog, you want to find Kc for the following reaction:
2NO2(g) ⥫⥬ N2(g) + 2O2(g)             K c = ?

Use the following data to find the unknown K c:
1/2 N2(g) + 1/2 O2(g) ⥫⥬ NO(g)                               K  c = 4.8×10−10
                 2NO 2(g) ⥫⥬ 2NO(g) + O2(g)                  K c = 1.1×10−5
