Question

For the reaction, $CH_{4}(g)+2H_{2}S(g) \rightleftharpoons CS_{2}(g)+4H_{2}(g)$, at 1173 K, the magnitude of the equilibrium constant, Kc is 3.6. For each of the following composition, decide whether the reaction mixture is at equilibrium. If it is not, decide to which direction the reaction should go:
(i) [$CH_{4}$] = 1.07 M, [$H_{2}S$] = 1.20 M, [$CS_{2}$] = 0.90 M, [$H_{2}$] = 1.78 M
(ii) [$CH_{4}$] = 1.45 M, [$H_{2}S$] = 1.29 M, [$CS_{2}$] = 1.25 M, [$H_{2}$] = 1.75 M
