• rate of reaction formula

  ROR = (amount of product or reactant formed) / time
• rate of reaction


  is the time taken for a reaction to occur

  amount of reactant used up or the amount of product formed
• 3 ways to measure ROR

  • precipitation
  • mass change
  • vol of gas given off
• collision theory - particles only react when they collide
• activation energy 


  minimum energy needed for a particle to react when colliding
• factors that affect the ROR based off of collision theory

  • temp
  • conc (for liquid) + pressure (for gas)
  • SA to vol ratio
  • catalyst
