In both sets, the cation with the smaller charge (i.e. Fe2+ in set I and Li+ in set II) will have the larger hydration energy. This is because the smaller charge density allows for stronger interactions between the cation and surrounding water molecules, resulting in a more negative hydration energy. Therefore, Fe³⁺ in set I and Li⁺ in set II would be expected to have the larger hydration energies.
