kinds of enthalpy

Lattice enthalpy one mole of a solid ionic lattice is formed from its gaseous ions under standard conditions
enthalpy change of atomisation one mole of gaseous atoms is formed from its element in its standard states
ionisation energy one mole of gaseous 1+ ions is formed from gaseous atoms
electron affinity one mole of gaseous 1- ions is formed from gaseous atoms
hess' law if a reaction can take place by more than one route and the initial and final conditions are the same, the total enthalpy change is the same for each route
standard enthalpy chance of formation the enthalpy change that takes place when one mole of a compound is formed from its constituent elements in their standard states under standard conditions
combustion one mole of a substance undergoes complete combustion in oxygen with all substances in standard states
hydration one mole of gaseous ions become dissolved in water
solution one mole of an 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
dissociation enthalpy change when one mole of covalent bonds is broken in the gaseous state
