--Understand that reactions occur because of collisions between molecules
--Know how reaction rates are affected by surface area, temperature and concentration
--Know how a catalyst affects a reaction and its activation energy
--Know the difference between a heterogeneous and a homogeneous reaction
--Know how to write the equilibrium expression (K) for homogeneous and heterogeneous reactions
--Understand why solids and liquids in an equilibrium expression have a value of 1
--Know how to calculate and equilibrium expression when numerical values are given
--Know how conditions affect the equilibrium of a reaction such as adding or removing reactants and products, adding or removing energy
