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.
The enthalpy difference between the reactants and the products is equal to the amount of energy released to the surroundings. A reaction in which energy is released to the surroundings is called an exothermic reaction. In this type of reaction the enthalpy, or stored chemical energy, is lower for the products than the reactants.
