Born-Haber Cycle: The Energy Behind NaCl Formation

The video tutorial explains the lattice energy of sodium chloride using the Born Haber cycle, which involves six steps. It starts with the reverse reaction of sodium chloride formation, followed by the sublimation of sodium, bond dissociation of chlorine, ionization of sodium, formation of chloride ions, and finally, the formation of sodium chloride crystal. The lattice energy is calculated using Hess's law, resulting in a value of -786 kJ/mol, indicating an exothermic process.
