Q. Lattice energy of an ionic compound depends upon :

NTA AbhyasNTA Abhyas 2022

Solution:

Lattice energy is the amount of energy change on formation of one mole of an ionic compound from its gaseous state.
Lattice Energy $\propto \frac{q_{1} q_{2}}{r_{c} + r_{a}}$
Where $q$ represents charge of ion and $r$ represent radius of ion.
Lattice energy does not dependent packing of ions.
