Final answer:
The Born-Haber cycle is a thermochemical cycle used to calculate the lattice energy of an ionic solid. It breaks down the formation of the ionic solid into individual steps, such as the formation of gaseous ions and the assembly of the ionic solid.
Step-by-step explanation:
The Born-Haber cycle is a thermochemical cycle that describes the process of forming an ionic solid from its component elements in a stepwise manner. It is used to calculate the lattice energy, which is the energy released when gaseous ions combine to form an ionic solid. The Born-Haber cycle is based on Hess's law and involves breaking down the formation of the ionic solid into a series of individual steps, such as the formation of gaseous ions and the assembly of the ionic solid.
