Based on Hess's law Born and Haber in 1919 developed a simplified and cyclic method to correlate lattice energies of ionic crystals to other thermodynamic data. For example, the net energy changes during the formation of sodium chloride from metallic sodium and chlorine gas can be represented by DHf·
The overall process is thought to take place in following intermediate steps:
Intermediate steps
(i) Metallic sodium into gaseous sodium atom
The energy required per mole of sodium is 'enthalpy of sublimation' which is represented by (Hs). This step is energy consuming process.
