What happens to the value of the equilibrium constant (Kc) for a reaction if the reaction is reversed?
Answer Details
If a reaction is reversed, the equilibrium constant (Kc) for the reversed reaction becomes the reciprocal of the original equilibrium constant. For a reaction: A + B ⇌ C + D The equilibrium constant Kc = [C][D]/[A][B] For the reversed reaction: C + D ⇌ A + B The equilibrium constant Kc(reversed) = [A][B]/[C][D] Thus, Kc(reversed) = 1/Kc.
