For the Dissociation Reaction of the Acid HF: HF(aq) $\Delta$ S Is Observed to Be Negative

question 2

Multiple Choice

For the dissociation reaction of the acid HF: HF(aq) H⁺(aq) + F^-(aq)
$\Delta$ S is observed to be negative.The best explanation is:

• A)This is the expected result since each HF molecule produces two ions when it dissociates.
• B)Hydration of the ions produces the negative value of \(\Delta\)S.
• C)The reaction is expected to be exothermic and thus \(\Delta\)S should be negative.
• D)The reaction is expected to be endothermic and thus \(\Delta\)S should be negative.
• E)None of these can explain the negative value of \(\Delta\)S.
