WebDecomposition reactions can be exothermic or endothermic, depending on the chemical energy of the substances. If the chemical energy of reactants are greater than products that time the reaction is exothermic with negative ( ΔH) and at that time, the product is more stable than reactant.

WebThis is called an endothermic reaction. If heat flows from the system to the surroundings, the reaction gave off energy. Therefore the change in enthalpy for the reaction is negative and this is called an exothermic reaction.
