Reactivity 1. What drives chemical reactions? Reactivity 1.1—Measuring enthalpy changes Reactivity 1.1.1—Chemical reactions involve a transfer of energy between the system and the surroundings, while total energy is conserved. Reactivity 1.1.2—Reactions are described as endothermic or exothermic, depending on the direction of energy transfer between the system and the surroundings. Reactivity 1.1.3—The relative stability of reactants and products determines whether reactions are endothermic or exothermic. Reactivity 1.1.4—The standard enthalpy change for a chemical reaction, ΔH⦵, refers to the heat transferred at constant pressure under standard conditions and states. It can be determined from the change in temperature of a pure substance.

Reactivity 1.2 - Energy cycles in reactions Reactivity 1.2.1 - Bond-breaking absorbs and bond-forming releases energy. Reactivity 1.2.2 - Hess’s law states that the enthalpy change for a reaction is independent of the pathway between the initial and final states. Reactivity 1.2.3 - Standard enthalpy changes of combustion, ΔHc ⦵, and formation, ΔHf ⦵, data are used in thermodynamic calculations. Reactivity 1.2.4 - An application of Hess’s law uses enthalpy of formation data or enthalpy of combustion data to calculate the enthalpy change of a reaction. Reactivity 1.2.5—A Born–Haber cycle is an application of Hess’s law, used to show energy changes in the formation of an ionic compound.
