Expert Solution
Step 1

Lattice energy is simply expressed by : 

U ~ Z+Z-/(r+ + r-) means greater is the product of opposite charges and smaller is the interionic radius more exothermic will be the Lattice energy. 

Hydration energy is directly proportional to the ionic potential (it is ratio of cationic charge/cationic radii) of cation.
