Vedclass · Answer

(D) The lattice energy $(U)$ of an ionic crystal is defined as the energy released when gaseous ions combine to form one mole of the solid ionic crystal.According to the Born-Landé equation,the lattice energy is inversely proportional to the inter-ionic distance $(r_0)$.Since the inter-ionic distance $r_0$ is the sum of the ionic radii of the cation $(r_c)$ and the anion $(r_a)$,we have $r_0 = r_c + r_a$.Therefore,the lattice energy $U$ is proportional to $\frac{1}{(r_c + r_a)}$.

$AB$ is an ionic solid. The ionic radii of $A^{+}$ and $B^{-}$ are respectively $r_c$ and $r_a$. Lattice energy of $AB$ is proportional to:
