Emp Ea Energ

·
There are no particles with no energy atall

·
The area under the curve represents the total no. of particles

·
The peak ofthe the energy thatmore particles

have than any other eners/Emp:mostprobable
· The activation eners can be shown. Often only a small

proportion ofmolecules have eners, activation eners

· When particles collide with each other they sain or


lose energy. The individual particles energy is always changing

Colission Theors/Rate ofReaction

· Particles mustcollide with sufficientenergy to react

and atthe correct orientation

·
Rate of Reaction is a measure of how fasta reaction

takes place
· itis defined as the change in concentration of
a


reactantor product per unit time
