FACTORS AFFECTING EQUILIBRIUM LE CHATELIERS PRINCIPLE

If a chemical system at equilibrium is disturbed by a change of concentration, pressure, or temperature, the system tends to counteract this change in order to reestablish a new equilibrium. In a chemical equilibrium, this principle is called Le Chatelier s principle. 

Henry-Louis Le Chdtelier was a French chemist. He devised Le Chdtelier s principle, which explains the effect of a change in conditions on a chemical equilibrium. He also worked on the variation in the solubility of salts in an ideal solution. 

When SO2 is added to the system, the first equilibrium system is disturbed and a new equilibrium state is established. 

If some amount of product, SO3, is added to the system, the concentration of product increases. Thus, the reaction shifts towards the reactants to decrease the concentration of products and to establish a new equilibrium state. 

When 3 mol of O2 are added to the container, in time, a new equilibrium is established.
