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
A +M ?A* + M
A +A ?A* + A
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)© BrainMass Inc. brainmass.com October 10, 2019, 4:21 am ad1c9bdddf
Here, I provided detailed steps how to use lindemann mechanism to find out the reaction kinects.
