Unit 1

On completion of the unit you should be able to:

  1. Demonstrate awareness that reactions occur at differing rates.
  2. Experimentally determine rate of a reaction.
  3. Demonstrate knowledge of collision theory.
  4. Apply collision theory to explain how reaction rates can be changed.
  5. Analyze the reaction mechanism for a reacting system.
  6. Represent graphically the energy changes associated with catalyzed and uncatalyzed reactions.
