Enthalpy of Formation
The enthalpy change when 1 mole of a substance is formed from its constituent elements, with all reactants and products in their standard states under standard conditions.
1 of 10
First Ionisation Enthalpy
The enthalpy change for the removal of 1 mole of electrons from 1 mole of gaseous atoms to produce 1 mole of singly charged positive ions in the gas phase.
2 of 10
Enthalpy of Atomisation
The enthalpy change for the formation of 1 mole of gaseous atoms from an element in its standard state.
3 of 10
Bond Dissociation Enthalpy
The enthalpy change required to break 1 mole of a specific bond in a specific compound in the gas phase.
4 of 10
Mean Bond Dissociation Enthalpy
The average of the bond dissociation enthalpies for a given bond measured over many compounds.
5 of 10
Electron Affinity
The enthalpy change when 1 mole of electrons is added to 1 mole of gaseous atoms to form 1 mole of gaseous negative ions.
6 of 10
Lattice Formation Enthalpy
The enthalpy change when 1 mole of an ionic solid is formed from its constituent gaseous ions.
7 of 10
Lattice Dissociation Enthalpy
The enthalpy change when 1 mole of an ionic solid is turned into its constituent gaseous ions.
8 of 10
Enthalpy of Hydration
The enthalpy change when 1 mole of a gaseous ion forms in a hydrated ion.
