Lyndon's Review #8B

Postby Emily Warda 2L » Sun Mar 18, 2018 10:07 am

From the rate law above, describe what must occur between the reactants in terms of the collision model and activated complex model. Explain the effect of increasing temperature.

What would be a sufficient answer to this question if asked on the exam?

Activated complex model = transition state model. He said it would be sufficient to state "As temp increases, so does the avg. # of molecular collisions. In order for a rxn to occur, the molecules must not only collide but must collide with the correct orientation. This is given by A (pre exponential factor) which determines the frequency of these favorable collisions".

Hi Emily,

That question was more for me to be able to discuss collisions, orientations, activation energy, etc. Remember that temperature increases the number of collisions. Discussing the above concepts would be sufficient. Also keep in mind that I put that question there so we could go ovee the concepts, not because I think an actual test question would look like that. Test questions will likely be more specific.
