Winter 2016 Final, 4B [ENDORSED]

[Molly Laviano 3N]

Part B of question 4 asks us to determine which proposed reaction mechanisms are valid and which step within the mechanism is the slow, rate-limiting step.

My questions...
We cannot have an intermediate in our rate law, correct?
To get rid of an intermediate, do we use the equation for the equilibrium constant K to solve for the concentration of the intermediate in terms of the concentrations of the reactants/products?

Thanks!!
