Unformatted text preview: Le-Chatelier’s Principle
Once an equilibrium is established, no further change is apparent
as long as the external conditions remain unchanged.
On changing the external conditions, whether the equilibrium will
shift towards the reactants or the products can be predicted by the
application of Le-Chatelier’s principle which states that
When a stress (change in concentration, temperature or total
pressure) is applied to a system at equilibrium, the system readjusts
so as to relieve or offset the stress.
