Which is the correct equilibrium constant expression for the following reaction?
Fe2O3(s) + H2(g) —> Fe(s) + H2O(g)
K = [H2O]3 / [H2]3
K = [Fe2O3] [H2]3 / [Fe]2[H2O]3
K = [Fe]2[H2O]3 / [Fe2O3] [H2]3
K= [Fe] [H2O] / [Fe2O3] [H2]
K = [H2O] / [H2]

The equilibrium constant expression for the reaction BrF5(g) —> Br2(g) + F2(g) is
Kc = [Br2] [F2] / [BrF5]
Kc = [BrF5]2 / [Br2][F2]5
Kc = [Br2] [F2]5 / [BrF5]2
Kc = 2[BrF5]2 / ([Br2] × 5[F2]5)
Kc = [Br2] [F2]2 / [BrF5]5

What is the Keq expression for this reaction?
2 NO(g) + O2(g) ⇌ 2 NO2(g)
Kc = [NO2]2 / [NO]2 [O2]
Kc = [NO]2 [O2] / [NO2]2
Kc = [NO]2 [O2] [NO2]2
Kc = [NO2]2 / [NO]2 + [O2]
