Answer:
ΔS < 0
ΔH < 0
Explanation:
Recall that the process is crystallization. Crystallization involves conversion of aqueous ions back to solid. This process decreases the entropy of the system hence ΔS is negative.
But remember that a process is only spontaneous when ΔG <0 (negative). From;
ΔG = ΔH - TΔS
If ΔS is negative, then (-TΔS) must be positive since ΔS is negative. The only way to make the process spontaneous is to make ΔH negative so that ΔG also becomes negative.
