What is the correct expression for the equilibrium constant Kc for a reaction where the products are H2O and the reactants are H2, given that both have a coefficient of 1?
Kc = [H2O] / [H2]^2
Kc = [H2] / [H2O]
Kc = [H2O]^2 / [H2]
Kc = [H2O] / [H2]

If the equilibrium constant Kc for a reaction is 2.41 x 10^-2, and the change in moles of gas (Δn) is -2, what is the expression for Kp?
Kp = Kc / (RT)^-2
Kp = Kc * (RT)^-2
Kp = Kc / (RT)^2
Kp = Kc * (RT)^2
