Statement - I: The lattice energy of superoxide of alkali metals increases with an increase in the size of the metal ionStatement - II: Lattice energy is directly proportional to size of the metal ion

Superoxide formula of alkalimetal MO2As the size of metal ↑es the stability of superoxide ion (O2-) by the M+ ion ↑es and hence stability of super Oxide ↑es and hence lattice energy ↑esstability Order: LiO2 < NaO2 < KO2 < RbO2 < CsO2Hint: A large size cation will stablise the large size anion(O2-)In generalStatement - I is correct & statement - II is in correct
