Le Chatelier

• Addition of reactant


  Product concentration increases

  Shift forward
• Addition of product


  Reactant concentration increases

  Shift backward
• Removal of reactant


  Product concentration decreases

  Shift backward
• Removal of product


  Reactant concentration decreases

  Shift forward
• Smaller number of molecules will be favored


  Decrease in volume

  Increase in pressure
• Larger number of molecules will be favored


  Increase in volume

  Decrease in pressure
• If the total number of molecules of the reactants and products are equal, a volume change will have no effect
• Endothermic

  Reactant
• Exothermic

  Product
• Endothermic - If temperature increases

  Forward reaction will be favored
• Endothermic - If temperature decreases

  Backward reaction will be favored
• Exothermic - If temperature increases

  Backward reaction will be favored
• Exothermic - If temperature decreases

  Forward reaction will be favored
