Which is the correct equilibrium constant expression for the following reaction?
Fe₂O_3(s) + 3H_2(g) —> 2 Fe_(s) + 3H₂O_(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 = [H₂] / [H₂O]

The equilibrium constant expression for the reaction 2BrF_5(g) —> Br_2(g) + 5 F_2(g) is

Kc = [Br₂] [F₂] / [BrF_5]

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

The equilibrium between carbon dioxide gas and carbonic acid is very important in biology and environmental science. CO_2(g) + H₂O_(l)—> H₂CO3(aq)
Which one of the following is the correct equilibrium constant expression (Kc) for this reaction?

Kc= 1/ [H₂CO₃]

Kc= [CO₂]/ [H₂CO₃]

Kc= [H₂CO₃] / [CO₂]

Kc= [CO₂] [H₂O] / [H₂CO₃]

Kc= [H₂CO₃] / [CO₂] [H₂O]
