Collision Theory and Activation Energy

I can describe the role of collisions, energy and particles in chemical reaction.

Collision Theory• Reactants must interact with enough

energy to break the chemical bonds to start the reaction

• To do this: • They must have enough speed

(kinetic energy) to break the bonds

• Correct orientation to break the bonds

Collision Theory and Activation Energy

I can describe the role of collisions, energy and particles in chemical reaction.

Activation Energy• The minimum amount of energy

needed to start the reaction
