2 NO2(g) ⇌ N2(g) + 2 O2(g) Kc = ?
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
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
