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

A. a spontaneous reaction
B. an endothermic reaction
C. an exothermic reaction
D. a reversible reaction

Correct Answer:

Option B – an endothermic reaction

Explanation

When the hydration energy is greater than the lattice energy, then the heat change is positive (i.e endothermic).
