reaction mechanisms are the
|
-series of individual elementary steps that convert reactants to products
-rate determining step |
|
|
rate determining step
|
the slowest step, which determines the rate law
|
|
|
unimolecular
|
Rate=k[A] first order rate law
|
|
|
bimolecular
|
Rate=k[A][B] or R=[A]^2- second order
|
|
|
termolecular
|
very rare Rate=k[A]^2[B]- third order
|
|
|
If rate law shows fractional or inverse orders this is
|
funky behavior!- means pre-equilibrium step before reaction
|
|
|
Any elementary step occurring after the reaction is
|
not reflected in the rate law
|
|
|
Reaction mechanism proposal:
|
-must obey experimentally determined rate law
-elementary steps, when added, MUST equal overall reaction of reactants to products -any catalyst must be regenerated |
|
|
cannot leave a what in a rate law?
|
a reactant intermediate
