The standard free energy change for the hydrolysis of ATP to ADP + P_i is -7.3 kcal/mol. From this information, one can conclude that the

Question

Quizplus · Accepted Answer

The negative standard free energy change (-7.3 kcal/mol) indicates that the reaction is exergonic, meaning it releases energy. Therefore, the correct option is (E) reaction is exergonic. Choice A is incorrect because the system will eventually reach equilibrium. Choice B is incorrect because it implies that the hydrolysis of ATP is an unfavorable reaction, which is not the case. Choice C is incorrect because the reaction releases energy. Choice D is incorrect because endergonic reactions require energy, whereas this reaction releases energy.
