Is it possible to have more than one chemical mechanism which is consistent with an observed kinetic mechanism? If you are told that a reaction goes via a particular chemical mechanism, can you derive more than one kinetic mechanism which is consistent with this mechanism?

Answer #1

There is a possibility of more than one mechanism possible for explaining the mechanism of reaction.

A mechansim is acceptabl;e if the sum of elementary steps give the overall balanced reaction. The mechansim has to be consistent with rate law which is determied experimentally.

IWhen there are more than one step for describingt the mechanis, the slowest step wil be the rate determining s

When there is no slowest step, the psuedo steady state approximation wll be used to determine the rate law for a multistep mechanism.
