Carbon dioxide and water react to form methane and oxygen, like this: CO2(g) + 2H2O(g) → CH4(g) + 2O2(g) The reaction is endothermic. Suppose a mixture of CO2, H2O, CH4, and O2 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.
