  The reaction 2AB + B2 ----->2AB2 has rate = k[AB]2[B2]. Which of the following mechanism is consistent with that rate law?

  1. AB + B2 <-----> AB3(fast, equilibrium)

    AB + AB3 -----> 2AB2(slow)

  2. 2AB -----> A2B2(slow)

    B2 + A2B2 ----->A2B4 (fast)

    A2B2 -----> 2AB2(fast)

 

Answer

  1. The mechanism described in (a) agrees with the rate law.
