Question

The equilibrium constant (kc) for the reaction 2HCl(g) =H2(g)+Cl2 (g) is 4×10^-34 at 25°C. What is equilibrium constant for the reaction: H2 (g) + CI2 (g) = 2HCI (g) at the same temperature?

Answer 1

Since the reactions are inversed, the equilibrium constants will be inversed

Thus kc = 1/4*10^-34 = 2.5*10^33
