Orders are
the number of species in the rate determining step
The rate of reaction is dependent on the
slowest step, the ‘rate determining step’
rate=
k[A]^x[B]^y
How do you know when a reaction mechanism consists of more than one step?
When not all of the reacting molecules appear in the rate equation
units of rate constant?
mol^-(n-1)l(n-1)s^-1 (where n is the overall order of the reaction)
