(a) Interpretation: The direction of the reaction C(s) + H 2 O(g) ⇌ CO(g) + H 2 (g) when the volume is increased should be predicted. Concept introduction: Le Chatelier’s principle states that if a change in pressure, temperature or concentration of reactant or product is applied to a system in equilibrium, the equilibrium shifts in such a way to counteract that change. Boyle’s law states that the pressure of a given mass of an ideal gas is inversely proportional to its volume at constant temperature.
