essential
* feature of the model is that, although a molecule might have
enough energy to
react, that energy is distributed over all the modes of motion of
the molecule, and
reaction will occur only when enough of that energy has migrated
into a particular
location (such as a bond) in the molecule
*molecule consists of s identical harmonic oscillators, the
principal conclusion is that the Kassel form of the unimolecular
rate constant for the decay of the energized molecule A* to
products is
E ≥ E*
S=3N-6=3*5-6=9
