For sodium chloride the equation is; Notice the difference between the equation above and that of the lattice enthalpy, which forms the lattice from gaseous ions.

The Cycle Is Now Complete;

Enthalpy of formation of sodium chloride crystal from sodium and chloride is given as, total enthalpy = enthalpy of sublimation + enthalpy of dissociation + enthalpy of ionization + electron gain enthalpy + lattice energy. For sodium chloride the equation is; The born haber cycle must begin with the elements in their standard states and arrive finally at the ions in position within 1 mole of a lattice.
