Vedclass · Answer

(B) Lattice enthalpy of an ionic solid is defined as the energy required to completely separate $1 \ mol$ of a solid ionic compound into its gaseous constituent ions.For $NaCl_{(s)}$, the process is represented as:$NaCl_{(s)} \longrightarrow Na^{+}_{(g)} + Cl^{-}_{(g)}$Thus, the enthalpy change of this reaction $(\Delta_r H)$ corresponds to the lattice enthalpy of $NaCl_{(s)}$.

$\Delta_r H$ of which reaction correctly represents the lattice enthalpy of $NaCl_{(s)}$?
