    As in exothermic reactions Heat is Generated ,the energy to give away the heat comes from the bonding energy of the reactants..and the answer will be less than the reactants..

    Bonding energy of reactants=Bonding energy of product +HEAT If heat>0 then Bonding energy of reactants>Bonding energy of product

    no ,that is not necessary,product's BONDING ENERGY will be lesser not the NO. OF PRODUCTS..

    Look in digestion of food you have many chemical reactions going on in your organs,and with the help of these reactions only food is broken into smaller parts. according to me the answer will be melting of ice as only the STATE OF MATTER is changing not matter itself.:)
