Question

Consider the air pollutants NO and NO2, contributors tophotochemical smog. Both can be formed by the reation betweenatmospheric nitrogen and oxygen. At 25 C,

N2(g)+O2(g)----2NO(g)K1=4.2E-31 (1)

N2(g)+2O2(g)----2NO2(g) K2=1.0E-18(2)

A) Wtire the equilibrium constant expression for the formationof two moles of NO at 25 C

B) CalculateK for the formation of one mole of NO at 25 C

C) Caluculate K for the decomposition of one mole of NO2 at 25C

D) Calculate K for the following reaction at 25 C

2NO(g)+O2(g)----2NO2(g)
