Concept introduction:
Lattice energy is the amount of energy needed for the conversion of one mole of an ionic solid to its constituent ions in the gaseous form.
The higher the value of lattice energy for a compound, the higher is its stability.
Born–Haber cycle is the method of calculating the lattice energy of a compound using different values of its constituent elements.
The steps to calculate lattice energy using Born–Haber cycle are given below:
The enthalpies of the formation of the metal as well as the non-metal are to be added.
The ionization energy of the metal is added, and electron affinity is subtracted from the calculated value.
The mode of the enthalpy of formation of the required compound is added to the above value.
