The state achieved when the forward and reaction rates occur simultaneously at the same rate and the concentration of the products and the reactants remains constant
Le Chateliers Principle
If factors affecting equilibrium are changed, equilibrium will shift in the direction that tends to cancel the effect of the change.
Factors affecting equilibrium
Concentration
Increases in concentration = system tries to decrease it
If forward reaction is favoured, conc. of products increases, conc. of reactants decreases
If reverse reaction is favoured, conc. of reactants increases, conc. of products decreases
