Question

What is lattice enthalpy of an ionic crystals? Give the relation.

Open in App

Solution

Lattice energy is the energy released when on mole of an ionic crystal is formed from one mole of their constituent ions . Greater the value of lattice energy, more stable is the ionic compound. The lattice energy of sodium chloride is -185 kcal/mole. The negative sign indicates that the process is exothermic process and that the energy of the system is lowered as the ionic solid is formed.
