Options

A. hydration energy of `Na_(2)SO_(4)` is more than of its lattice energy
B. attice energy of `BaSO_(4)` is more than its hydration energy
C. Both (a) and (b)
D. None of the above

Answer

c

Explanation

For dissolution hydration energy must be more higher (-ve) value than of lattice energy .Thus , (c ) is the correct answer .
