Question

Methane and hydrogen sulfide react to form carbon disulfide and hydrogen, like this:

CH4(g)+2H2S(g)→  CS2(g)+4H2(g)

Suppose a mixture of CH4, H2S, CS2 and H2 has come to equilibrium in a closed reaction vessel. Predict what change, if any, the perturbations in the table below will cause in the composition of the mixture in the vessel. Also decide whether the equilibrium shifts to the right or left.
