8. Collision Theory and Activation Energy I can describe the role of collisions, energy and particles in chemical reaction. Collision Theory Activation Energy

9. 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
