  1. THE COLLISION THEORY

  2. For the reaction A + B  C, A and B must collide • For the reaction A  B + C, A must collide with itself or with the walls of the container

  3. Effective Collisions • An effective (successful) collision is a collision that occurs with enough energy and with particles aligned correctly • In an ineffective (unsuccessful) collision, the colliding particles remain unchanged

  4. Rate of the reaction α the # of collisions; that is, the rate increases if the # of collisions increases • Rate of the reaction α the % effective collisions; that is, the rate increases if the % that are successful increases

  5. During a collision, the sum of PE + KE remains constant; that is, as particles collide they slow down and KE decreases but PE increases

  6. Activation Energy

  7. Activation Energy: the minimum energy with which reactant particles must collide to produce an effective collision

  8. Activated complex: an unstable chemical species containing partially broken and partially formed bonds
