9. False. In a dynamic equilibrium the concentrations of reactants and products are
always constant.
10. False. If the equilibrium constant, K, is equal to 1, the position of equilibrium does
not favour products or reactants.
11. False. Haber’s addition of iron(III) oxide as a catalyst to the process of creating

12. True
13. False. An exothermic reaction that is at equilibrium will shift to the right when
products are removed.
14. True
15. False. The solubility product constant, Ksp, is a constant for a given substance under
specific conditions.
16. False. If the trial ion product, Q, is greater than the solubility product constant, Ksp,
a substance will precipitate from solution.
