    In the discussion of the Lindemann mechanism, it was assumed that the rate of activation by collisions with another reactant molecule, A, was the same with a non-reactant molecule, M, such as an inert gas. What if the rates of activation for these two process are different? In this case, the mechanism become

    k1
    A +M ?A* + M
    k-1

    k2
    A +A ?A* + A
    k-2

    k3
    A* ? P

    Demonstrate that the rate law expression for this mechanism is:

    R= (k3(k1[A][M]+k2[A]^2)/(k-1[M]+k-2[A]+k3)
