HELP PLEASE

Methane and water react to form hydrogen and carbon monoxide, like this: CH4(g)+H2O(g)3H2(g)+CO(g) The reaction is endothermic. Suppose a mixture of CH4,H2O,H2 and CO has come to equalibrium in a ciosed 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 shirts to the right or left
