Enthalpy definitions

Define standard enthalpy of formation
The enthaply change when one mole of a compound is formed from its constituent elements in standard conditions. With all the reactants and products in its standard states
1 of 6
Define standard enthalpy of combustion
The enthaply change when one mole of a substance is completely burned in excess oxygen
2 of 6
Define standard enthalpy of atomisation
Enthalpy change when one mole of gaseous atoms is formed from a compound in its standard states in standard conditions
3 of 6
Define first ionisation energy
Enthalpy change when one mole of electrons is removed from one mole of gaseous atoms to form one mole of gaseous 1+ ions
4 of 6
Define second ionsiation energy
Enthalpy chage when one mole of electrons is removed from one mole of gaseous 1+ ions to form one mole of gaseous 2+ ions
5 of 6
Define first electron affinity
Enthaply change when one mole of gaseous atoms gains one mole of electrons to form one mole gaseous 1- ions
