VA U YULLALUus, vul te reacals are kinetically stable. 4. Consider the dissociation reaction of the acid HF HF(aq) 2 H(aq) + F(ag) Why is AS negative? A) Each HF molecule produces two ions when it dissociates. B) The ions are hydrated. The reaction is expected to be exothermic, and AS thus should be negative. D) The reaction is expected to be endothermic, and thus AS should be negative. E) none of these . . .

Imagine a product favored chemical reaction happening in a living organism in which a substance D goes to E. It is known that the concentration of D remains well above zero and constant over time. Given that the reaction is product-favored, how is the concentration of D maintained? Give two possible reasons. How might the catalysis of the reaction maintain the concentration of D?
