2H2S(g) ? 2H2(g) + S2(g)
When heated, hydrogen sulfide gas decomposes according to the equation above. A 4.40 g sample of H2S(g) is introduced into an evacuated rigid 1.50 L container. The sealed container is heated to 583 K and 5.72x10^-2 mol of S2(g) is present at equilibrium.

a. Write the expression for the equilibrium constant, Kc, for the decomposition reaction represented above.

b. Calculate the equilibrium concentration, in mol L1-, of the following gases in the container at 583 K.
i. H2(g)
ii. H2S(g)

c. Calculate the value of the equilibrium constant, Kc, for the decomposition reaction at 583 K.

e. For the reaction H2(g) + ½S2(g) ? H2S(g) at 583 K, calculate the value of the equilibrium constant, Kc.
