Unimolecular Reactions: Unimolecular reactions proceed through the Lindemann mechanism:

  1) R + R --> R* + R
  2) R* --> P

where the first elementary step is rate determining and the steady-state approximation is valid.  Depending on the concentration of the reactant R, this reaction will either be first order in [R] or second order in [R].   

Radical Reactions: I'll talk more about these on Wednesday
