2. Which one of the following best explains why water is a monodentate ligand?

    

1. Select the statement below that is correct.

    

1. In recitation, you studied the electrochemistry involved in the "fruit clock". If an orange is used to power the fruit clock, which of the following statements is TRUE?

    

1. Consider the following reaction in aqueous solution,
   5Br^-(aq) + BrO₃^-(aq) + 6H⁺(aq) --> 3Br₂(aq) + 3H₂O(l)

   If the rate of appearance of Br₂ at a particular moment during the reaction is 0.025 M s^-1, what is the rate of disappearance (in M s^-1) of Br^- at that moment?

    

• For the following reaction of hypochlorous acid (HOCl) with water,
  HOCl + H₂O <==> H₃O⁺ + OCl^-

  what would be the effect of adding sodium hypochlorite (NaOCl) to the reaction at equilibrium?

  1. The concentrations of both HOCl and H₃O⁺ would increase.
  2. The concentrations of both HOCl and H₃O⁺ would decrease.

1. For a process at 451 K and constant pressure,
