he following reactions start at equilibrium. A stress is added and the position of equilibrium shifts. After the indicated stress is added which of the following reactions will proceed towards products? The added stress is the part listed inside the braces {} HINT: You must be careful now because this is a trick question. To answer this question, I suggest that you first write the equilibrium expression. Then recall what must be true for the concentration of pure solids and liquids in an equilibrium expression. See section Heterogeneous Equilibria, p.130 in the notes.
