How does the collision theory relate to the rate of a chemical reaction?
Collision theory says that chemical reactions occur by the collisions between atoms and molecules, so the more collisions the faster the rate of the chemical reactions.
The collision theory says that chemical reaction only occur if there are collisions of the right energy levels between molecules and atoms.
It follows that if the molecules collide more often that this will increase the rate of reaction.
The higher the temperature the more kinetic energy molecules and atoms have. The more kinetic energy the molecules have the faster they move and the more collision will occur increasing the rate of the reaction.
Catalysts can lower the energy required for the collision to effect a chemical reaction. So a catalyst can increase the rate of the reaction.
