Rate and extent of reactions

• Le Chatelier’s 


  conditions of an equilibrium are changed, the equilibrium will shift its position in order to counteract that change
• Temperature increases 


  Shifts to favour the endothermic side
• Temp decreases 


  shifts to favour the exothermic side
• Increasing pressure 


  Shifts to the side with fewer molecules
• Decreased pressure 


  shifts to the side with greater molecules
• High concentration 


  shifts to the side of fewer reactants
• Low concentration 


  shifts to the side of more reactants
• Catalysts


  have no effect on equilibrium, both the forward and backward reaction are sped up equally
