Q. When Ionic compounds such as NaCl dissolves in water, the sodium ions are surrounded by six water molecules. The bound water molecules exchange with those in bulk solution as described by the reaction involving 18O-enriched water: 1. Na(H2O)6+ (aq) → Na(H2O)5+ (aq) + H2O (l) 2. Na(H2O)5+ (aq) + H218O (l) → Na(H2O)5(H218O)+ (aq) A. What is the rate law if the first step is the rate-determining step? B. Sketch a reaction-energy profile for this reaction mechansim.

Q. The graphs shown here are called potential energy diagrams. They show the potential energy of a system as it changes from reactants to products. The first graph shows the uncatalyzed reaction (figure 1); the second graph shows the catalyzed reaction (Figure 2). What is the value of the enthalpy change of the uncatalyzed reaction in reverse? Express your answer to three significant figures and include the appropriate units.
