Which one of the following is applied to calculate lattice energy indirectly?
Correct answer: A. Born-Haber cycle
- A. Born-Haber cycle
- B. Bohr theory
- C. Le-Chatelier principle
- D. All of them
Explanation
Option A is correct.The Born-Haber cycle is used to calculate the lattice energy of an ionic compound indirectly. The Born-Haber cycle is a thermodynamic cycle that starts with the elements in their standard states and ends with the formation of the ionic compound in its standard state. The lattice energy is the energy required to convert the gaseous ions of the ionic compound into the solid ionic compound.

About Lattice Energy
Lattice energy describes the energy released when gaseous ions form one mole of an ionic solid, or the energy required to separate that solid into gaseous ions, depending on the convention used. Its value depends mainly on ionic charge and radius and is calculated through Born-Haber cycles.
