Collision Theory

>Chemical reactions only occur when reacting particles collide with each other with sufficient energy. 

>The minimum amount of energy required to cause a reaction is called the activation theory.

>There are four important factors that affect the rate of reaction :

Temperature, Concentration, Surface area and Catalysts.  

Temperature:

> In a hot mixture the particles move more quickly- they collide more oftern and with greater energy, so more collisons…
