Multiple Choice
Indicate the statement(s) which is (are) true for the process:
Al+3(aq) + 3 OH-(aq) → Al(OH) 3(s)
If it occurs in a closed container.
I.ΔS increases because the final molecule is more complicated.
II.Entropy decreases because the product is in the solid phase.
III.The two ions achieve a high degree of order as they crystalize,therefore ΔS is positive.
IV.Entropy of the system is unchanged because the system is sealed and at a constant temperature.
A) I and II
B) I and III
C) II only
