Explanation Enthalpy is a thermodynamic property. It is equal to the sum of the internal energy and the product of pressure and volume of a system. Under conditions of constant pressure, the energy of a system is known as its enthalpy. Thus, enthalpy is represented by H . △ H represents change in enthalpy. It is equal to the difference in the enthalpy of the final and the initial state of a system. In chemical reactions , it is equal to the difference in enthalpy of products and reactants. At constant pressure, the heat of reaction is the enthalpy change
