The lattice energy for NaCl cannot be measured directly, but using the Born-Haber cycle, it can be inferred. Let’s say the experimental enthalpy change of formation for NaCl is -411 kJ\/mol. Then, using Hess’s law, we can solve for the lattice energy.<\/p>\n
<\/p>\n
By inserting our values:<\/strong><\/p>\n <\/p>\n
Lattice Energy = +108 kJ\/mol (Sublimation) + +495.8 kJ\/mol (Ionization) + (+242 kJ\/mol \/ 2) (Dissociation) – 349 kJ\/mol (Electron Affinity) – 411 kJ\/mol (Formation)<\/p>\n
Lattice Energy = +108 + 495.8 + 121 – 349 – 411<\/p>\n
Lattice Energy = -735.2 kJ\/mol<\/p>\n
<\/p>\n
This result indicates that when Na\u207a and Cl\u207b ions come together to form the crystal lattice of NaCl, 735.2 kJ\/mol of energy is released, showing a strong exothermic reaction, which corresponds to a highly stable ionic solid.<\/p>\n
