. The following events must occur before a reaction can proceed:. The reactant particles must collide with each other.The collisions must be of enough energy to overcome the energy barrier', called the activation energy (more about this on the next slide).The reactants must form new bonds to prod

1. Factors Affecting the Rate of a Chemical Reaction 1. temperature
2. concentration
3. pressure (gases)
4. surface area
5. orientation (molecules must collide in a specific manner to form a chemical bond)
6. nature of the reactants (polar, non-polar, electronegativity, heterogeneous, homogeneous)
7. catalyst
