Homework Help: Chemistry - Reaction Mechanism

  1. Nov 18, 2009 #1
    1. The problem statement, all variables and given/known data

    "Given the rate law for the following equation is Rate = k[A][B2]
    2A + B2 ------> 2AB

    Suggest a mechanism for the reaction

    2. Relevant equations

    I have no clue; I was absent for 2 weeks and now have to teach myself the first two units, I've been able to teach myself rate law and order of the reaction and equilibrium stuff but I am lost on this.

    3. The attempt at a solution

    A + B = AB
    AB + AB = 2AB

    Any guidance would be nice.

    I'm also a student but i'm gonna try this, since the rate law stated that Rate = k[A][B2] so my assumption is

    A + B2 ---> AB + B
    B + A ----> AB

    since the rate law is Rate = k[A][B2] it should means that the slow steps consist of 1 mol of A and 1 mol of B2
