Energetics
infoWhy this? Enthalpy changes quantify the energy transferred in reactions, helping us evaluate fuels and other chemical processes. Calorimetry, Hess's law, and bond enthalpies provide complementary ways to measure or calculate these changes.
scheduleWhy now? Bonding and amount of substance allow us to explain energy changes through bond breaking and formation and express them per mole. Energy profiles support the forthcoming study of kinetics, while enthalpy calculations prepare us for Year 13 thermodynamics.
