STANDARD ENTHALPY OF FORMATION
Enthalpy change when one mole of a compound is formed from its elements in their standard state, under standard conditions.
STANDARD ENTHAPLY OF COMBUSTION
Enthalpy change when one mole of an element or compound in its standard state, reacts completely with oxygen under standard conditions.
The enthalpy change of a reaction is independent of the path taken provided the initial and final conditions remain the same.
STANDARD BOND DISSOCIATION ENTHALPY
Energy change when one mole of covalent bond is broken in the gaseous state.
FIRST IONISATION ENERGY
Energy required to convert one mole of gaseous atoms into gaseous ions with a single positive charge.
FIRST ELECTRON AFFINITY
Energy change when one mole of gaseous atoms is converted into gaseous ions with a single negative charge.
THE STANDARD ENTHALPY OF ATOMISATION
The heat change that accompanies the production of one mole of gaseous atoms from the element in its standard state.
THE STANDARD LATTICE ENTHALPY
The energy required to split up one mole of a solid crystal lattice into its gaseous ions.
THE STANDARD ENTHALPY OF HYDRATION
The heat change per mole for the hydration of the gaseous ion with enough water for there to be no further heat change on dilution.
THE STANDARD ENTHALPY OF SOLUTION
The enthalpy change when one mole of solute is dissolved in a solvent, forming an infinitely dilute solution.
The amount of disorder or randomness within a chemical system.
