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. WebThese guides are for use with the 2024 GCSE chemistry AQA syllabus. They can also be used for Trilogy Chemistry but do not revise the bits that say Chemistry only.
