Legal. Values of lattice energies for various solids have been given in literature, especially for some common solids. Rank the following compounds in order of increasing lattice energy. A- The order of increasing lattice energy is RbCl 0 \tag{4.2.1} \). Why Walden's rule not applicable to small size cations. When a salt, such as NaCl dissolves in water, the crystals disappear on the macroscopic The answer is 3406 kJ/mol. therefore depends on the charges on the ions and the distance between the centers of the
