What is the Keq expression for this reaction?    2 NO(g)  +  O2(g) ⇌  2 NO2(g)

Keq = [NO2]2 / [NO][O2]

Keq  =  [NO][O2] / [NO2]2

Keq  = [NO][O2] [NO2]2

Keq  = [NO2]2 / [NO]2 +  [O2]

N2O4(g) ↔ 2 NO2(g)
What is the concentration equilibrium constant expression?

Keq  = [NO2]2/[N2O4]

Keq  = [N2O4]/[NO2]2

Keq = [N2O4]2/[NO2]

Keq = [NO2]/[N2O4]2
