  • A reversible reaction is one which takes place in both forward and backward directions
  • As fast as the reactants are converted into products, the products products are converted back into reactants
  • Dynamic Equilibrium = Where the forward and backward reactions occur at the same rate
  • Le Chatelier's principle = If a system at equilibrium is subjected to a change, the equilibrium tends to shift so as to minimise the effect of the change
  • An equilibrium only applies as long as the system remains isolated
  • POE = Position Of Equilibrium 
  • POE can be altered by changing:

1. Concentration of the reactants or products
2. Pressure
