EXOTHERMIC REACTION

EXOTHERMIC REACTION

      In exothermic reaction the sum of heat content of reactants are large than the sum of heat content of products. Thus during product formation the excess amount of energy (heat) from the reactants released out from the the system to the surroundings, this reaction is exothermic reaction.

Consider the example below;
     
                A + B > D + C

 from the illustration above if the sum of heat content of A and B (reactants ) are large than thsum of heat content of D and C ( products) then the reaction will be exothermic reaction.
                                   
                                   

      There fore;
                Exothermic reaction is the chemical reaction which release heat (energy) to the surrounding when proceeding.

    Examples of exothemic reaction include;
       
          1). Combustion reactions

          2).mixing of water and strong acids such as concentrated sulphuric acid.
