Collision theory and activation energy.

Answer Text:
Collision theory and activation energy.
-The collision theory of reacting particles postulates
that:
-Reacting particles must collide before a chemical reaction occurs
-Not all collisions are effective/ result in chemical reaction
-Only those particles with sufficient energy result in effective collisions i.e. energy equal to or greater than the activation energy.
-Any factor, which increases the rate of a chemical reaction, does so by increasing the number of effective collisions;
Activation energy (EA):
- Is the minimum amount of energy required by reacting particles to cause a successful collision to form products;
- It refers to the energy an energy barrier that must be overcome by the reactants to be converted to products;
- This energy barrier determines the magnitude of the activation energy of the reactants;
