methods of measuring reaction rate
1. measure the rate at which a reactant is used up
  1. measure the rate at which a product is formed
collision theory
1. for a chemical reaction to happen the reactant particles must collide
  1. collisions with too little energy wont create a reaction
temperature and reaction rate
1. the reactant particles move more quickly
  1. they have more energy
    1. the particles collide more often
      1. the rate of reaction increases
concentration and reaction rate
1. the reactant particles become more crowded
  1. there is a greater chance of the particles colliding
    1. the rate of reaction increases
