A chemical reaction in which the hydration energy is greater than the lattice energy is referred to as?

A. A reversible reaction
B. A spontaneous reaction
C. An endothermic reaction
D. An exothermic reaction

Correct Answer:

Option D – An exothermic reaction

Explanation

In salts for which the hydration energy is higher than the lattice energy, solvation occurs with a release of energy in the form of heat. A reaction in which there is a release of energy as LIGHT OR HEAT is EXOTHERMIC.
