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. WebGCSE. AQA Chemistry. 4.6 The rate and extent of chemical change. 4.6.2 Reversible reactions and dynamic equilibruim. 4.6.2.2 Energy changes and reversible reactions. If a reversible reaction is exothermic in one direction, it is endothermic in the opposite direction. The same amount of energy is transferred in each case.
