Enthalpy of a reaction or energy change of a reaction D H, is the amount of energy or heat absorbed in a reaction. If the energy is required, D H is positive, and if energy is released, the D H, is negative.
In exothermic reactions, some of the reactants' potential energy or enthalpy is released into the surroundings, usually in the form of heat. As a result, the enthalpy of the products is less than the enthalpy of the reactants. The enthalpy change for an exothermic reaction is always negative.
