Enthalpy change that accompanies the formation of one more of an ionic compound from its gaseous ions under standard conditions. | Lattice enthalpy |
States that if a reaction can take place by more than one route and initial and final conditions are the same, the total enthalpy change is the same for each route. | Hess' Law |
Enthalpy change that takes place when one mole of a compound is formed from its constituent elements in their standard state under standard conditions. | Standard enthalpy change for Formation |
Enthalpy change that takes place when one mole of gaseous atoms forms from the element in it standard state. | Enthalpy change of atomisation |
Enthalpy change accompanying the removal of one electron from each atom in one mole of gaseous atoms to form 1+ ions. | First Ionisation Energy |
Enthalpy change accompanying the removal of one electron from each ion in one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions. | Second Ionisation energy |
Enthalpy change accompanying the addition of one electron to each atom in one mole of gaseous atoms to form one mole of gaseous 1- ions. | First electon affinity |
Enthalpy change accompanying the addition of one electron to each ion in one mole of gaseous 1- ions to form one mole of gaseous 2- ions. | Second electron affinity |
