Document Summary

Energy is required for these bonds to break. Then, subtract the sum of the enthalpies of formation of the reactants from the sum of the. ((cid:1866) (cid:3033) )(cid:3045)(cid:3032)(cid:3030)(cid:3047)(cid:3041)(cid:3047)(cid:3046) enthalpies of formation of the products r. = = (cid:1865) where m is the mass of water, c is the specific heat capacity of water, and is the change in the water"s temperature. If more energy is released than absorbed, the reaction is exothermic - there is a net release of energy absorption of energy. In exothermic reactions, the products contain less potential energy in their bonds than the reactants, and there is a net output of energy into the surroundings. In endothermic reactions, the products contain more potential energy in their bonds than the reactants, so there is a net input of energy to create an activated complex than the reaction releases into the surroundings. The extra energy is stored in the bonds of the products.
