Define lattice enthalpy of an ionic solid. Also give an example.

Explanation

Lattice enthalpy o fan ionic solid is defined as the energy required to separate one mole of a solid ionic compound into gaseous constituent ions.
For example, Lattice enthalpy of `NaCl " is " 788 kJ""mol^(-1)`
`NaCl(s)+788kJ mol^(-1) rarr Na^(+)(g)+Cl^(-)(g)`
