    Question For the reaction
    A+2B ---> E

    A. Give the rate law if the mechanism is:

    2A+B ---->C (slow)
    B+C -----> D+A (fast)
    D--------->E (fast)

    B. Give the rate law if the mechanism is:

    2A+B ------>C (fast)
    B+C -------> D+A (slow)
    D----------->E (fast)

    Solution Preview

    The rate depends on the slowest step

    A. Rate = k[A]^2 [B]

    B. Rate = k[B][C]
    Here [C] is an intermediate, so ...

    Solution Summary

    The rate law is given for reactions whose mechanisms are known.
