For each of the following equilibria, use Le Chatelier's principle to predict the direction of reaction when the volume is increased. [Part A] C (s) + H2O (g) --><-- CO (g) + H2 (g). [Part B] 2H2 (g) + O2 (g) --><-- 2H2O (g). [Part C] 2Fe (s) + 3H2O (g) --><-- Fe2O3 (s) + 3H2 (g). ((the possible answer choices for each part are: The reaction will go the products, reactants, or will remain at equilibrium))
