The catalytic converter in an automobile has to be able to convert NO2(g) produced in an engine into N2(g) and O2(g), according to the reaction:

NO2(g) ⇌ 1⁄2 N2(g) + O2(g)

The equilibrium constants (at 298 K) for the following reactions are known:

1⁄2 N2(g)+ 1⁄2 O2(g)⇌NO(g) Kc1 =6.6×10^-16

2 NO2(g) ⇌ 2 NO(g) + O2(g) Kc2 = 3.3 × 10^-13

a. What is value of Kc for the decomposition of NO2 at 298K?

b. Are the products favored at equilibrium?
