  • Enthalpy of Formation is the enthalpy change when one mole of a substance is formed from its constituent elements where all reactants and products are in standard states and under standard conditions
  • Enthalpy of combustion is the enthalpy change when one mole of a substance undergoes complete combustion with sufficient oxygen, where all reactants and products are in their standard states under standard conditions
  • Ionisation enthalpy is the enthalpy change to remove one electron from a species to form a positive ion and a electron in the gaseous state
  • Electron affinity is the enthalpy change when a electron is added to a atom in its gaseous state to form a negative ion.
  • Bond dissociation enthalpy is the enthalpy change when a covalent bond is broken into two free radicals in the gas state
  • Enthalpy of atomisation is the enthalpy change when one mole of gaseous atoms is formed from the element in its standard state
  • Enthalpy change is the change of heat energy under a constant pressure
  • Lattice enthalpy of dissociation is the enthalpy change when one mole of solid ionic lattice is separated into gaseous ions
  • Lattice enthalpy of formation is the enthalpy change when one mole of a solid ionic lattice is formed from its gaseous ions
  • Enthalpy of Solution is the Enthalpy change when one mole of a substance is dissolved in so much water the dissolved ions do not interact
  • Enthalpy of Hydration is the enthalpy change when one mole of gaseous ions forms aqueous ions
  • Energy cycle
