- 1Enthalpy of formation ∆HᶿfEnthalpy of formation ∆Hᶿf – Enthalpy change when one mole of a substance is formed from its constituent elements with all substances in their standard states.
- 2Enthalpy of combustion ∆HᶿcEnthalpy of combustion ∆Hᶿc – Enthalpy change when one mole of a substance undergoes complete combustion in O2 with all substances in their standard states.
- 3Ionisation Enthalpy ∆HᶿiEnthalpy of ionisation ∆Hᶿi– Enthalpy change when one mole of gaseous atoms loses one electron per atom to produce one mole of 1+ ions.
- 4Electron affinity ∆HᶿeaEnthalpy of electron affinity ∆Hᶿea– Enthalpy change when one mole of gaseous atoms gains one electron per atom to produce one mole of 1- ions.
- 5Enthalpy of atomisation ∆HᶿaEnthalpy of atomisation ∆Hᶿa– Enthalpy change when one mole of gaseous atoms is produced from an element in it’s normal state.
- 6Hydration enthalpy ∆HᶿhydHydration Enthalpy ∆Hᶿhyd– Enthalpy change when one mole of gaseous atoms becomes hydrated (dissolved in water).
- 7Enthalpy of solution ∆HᶿsolEnthalpy of solution ∆Hᶿsol– Enthalpy change when one mole of ionic solid dissolves in an amount of water large enough so that the dissolved ions are well separated and do not interact with each other.
- 8Bond dissociation enthalpy ∆HᶿdisBond dissociation enthalpy ∆Hᶿdis– Enthalpy change when one mole of covalent bonds is broken in the gaseous state.
- 9Lattice enthalpy of formation ∆HᶿLLattice enthalpy of formation ∆Hᶿsol– Enthalpy change when one mole of solid ionic compound is formed into it’s constituent ions in the gas phase.
- 10Lattice enthalpy of dissociation ∆HᶿLLattice enthalpy of formation ∆Hᶿsol– Enthalpy change when one mole of solid ionic compound is broken up into it’s constituent ions in the gas phase.
- 11Enthalpy of Vaporisation ∆HᶿvapEnthalpy of vaporisation ∆Hᶿvap– Enthalpy change when one mole of atoms is converted to the gaseous state.
