2 NO2(g)  N2(g) + 2 O2(g)              Kc = ? 


Given reactions:

Reaction 1:                  1/2 N2(g) + 1/2 O2(g)  NO(g)              Kc1 = 4.8x10-10

     Reaction 2:                   2 NO2(g) 2 NO(g) + O2(g)                 Kc2 = 1.1x10-5


Reaction 1: 1/2 N2(g) and 1/2 O2(g)  reactant side → reverse the equation.

                     NO(g)    1/2 N2(g) + 1/2 O2(g)                                 Kc1 = 1/(4.8x0-10) = 2.08x10-9

Problem Details

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
