Driving Force for Spontaneity of a Reaction

CHEM-IDHJK2

For the following reaction $NH_{4}NO_{3}(s) + H_{2}O(l) \leftrightarrow NH_{4}^{+}(aq) + NO_{3}^{-}(aq)$, at $25^{\circ}C$, $\Delta H^{\circ}=28.05 \space kj/mol$ and $\Delta S^{\circ}=108.7 J/mol K$.

What is the driving force behind the spontaneity of this reaction?

A

Enthalpy.

B

Entropy.

C

Both enthalpy and entropy.

D

Neither enthalpy or entropy.
