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.
Enthalpy of a reaction is defined as the heat energy change () that takes place when reactants go to products. If heat is absorbed during the reaction, is positive; if heat is released, then is negative. Let's understand this through an example. We can calculate the enthalpy change () for the following reaction:
