Web⚛ An energy profile is a diagram representing the energy changes that take place during a chemical reaction. ⚛ Enthalpy change, Δ H, is the amount of energy absorbed or released by a chemical reaction. (2) On an energy profile, the enthalpy change for the reaction is measured from the energy of the reactants to the energy of the products.
