Enthalpy change is the name given to the amount of heat evolved or absorbed in a reaction carried out at constant pressure. It is given the symbol ΔH, read as "delta H". Note: The term "enthalpy change" only applies to reactions done at constant pressure. The reaction enthalpy is calculated by subtracting the sum of enthalpies of all the reactants from that of the products.
