Describe the collision theory.

Factors affecting rate of reaction	Description	Diagram
Collision Frequency	Higher the frequency of collision, the higher the probability of successful collision.
Collision Geometry	Due to particles coming in different orientations it is necessary for the collision to take place successfully.
Number of particles with E ≥ Ea	In order for collision to take place particles must have a minimum amount of energy to overcome repulsion between molecules and to break some bonds in the reactants. Only particles with E ≥ Ea will successfully collide.
