Equilibrium Expressions

Solution: Which is the correct equilibrium constant expression for the following reaction?Fe2O3(s) + 3 H2 (g) <==> 2 Fe (s) + 3 H2O (g)a. Kc = [Fe2O3][H2] / [Fe] 2[H2O]3b. Kc = [H2] / [H2O]c. Kc = [H2O]3

Problem

Which is the correct equilibrium constant expression for the following reaction?

Fe2O3(s) + 3 H2 (g) <==> 2 Fe (s) + 3 H2O (g)

a. Kc = [Fe2O3][H2] / [Fe] 2[H2O]3

b. Kc = [H2] / [H2O]

c. Kc = [H2O]3 / [H2]3

d. Kc = [Fe]2[H2O]/ [Fe2O3][H2]3

e. Kc = [H2O]3 / [H2]3
