CHEMICAL EQUILIBRIUM

CHEMICAL EQUILIBRIUM

    There some reversible reactions which are forward and reverse reactions occur at the same time. At the beginning amount of reactants are at maximum, and amount of products are zero, as the reaction proceed the amount of reactants decrease and that of product increase untill, the equal amount of reactants and products obtained. At this condition the reaction said to be at equilibrium.

There fore ;
      Chemical equilibrium is the state at which the forward and backward reaction are proceeding at the same rate.
   Forward and backwards reaction proceed until equilibrium is mantained, is not static but it it is dynamic, means reactants form products (forward reaction) at the same rate as products react to form reactants (backward reaction) this process occur at equilibrium state and thus why equilibrium is dynamic and not static.
                       

FACTORS AFFECTING THE POSITION OF EQUILIBRIUM

French chemist Henri Louis Le Chatelier came up with a generalization which is commonly known as Le chatelier's principle,,, which states that;

"If stress is applied to a system at equilibrium, the system readjusts, if possible to reduce the effective of the stress."

  The principle means that if there is any change in the chemical equilibrium, position of equilibrium will change to overcome or counteract the change.

The following are factors which affect position of chemical equilibrium.

         1) Temperature

         2) concentration

         3) pressure

         4) catalyst
