9. Consider the dissociation reaction of the acidHF.
HF(aq) ⇌ H+(aq) + F-(aq)
Why is ΔS negative?
(A) The reaction is expected to be exothermic, and ΔS thus should be negative.
(B) The reaction is expected to be endothermic, and thus ΔS should be negative.
(C) Each HF molecule produces two ions when it dissociates.
(D) The ions are hydrated.
(E) none of these
