Which statement is true about exergonic reactions? a. in exergonic reactions, δg is positive due to the absorption of free energy. b. exergonic reactions use more free energy than the amount of energy they produce. c. exergonic reactions usually occur spontaneously because they require less energy of activation..

An exergonic reaction is any type of reaction where energy is released. These type of reactions happen spontaneously since the reactants lose energy and require less energy of activation. Based on this we can conclude that A is not the answer. With this information we can conclude that the correct answer is C, exergonic reactions usually occur spontaneously because they require less energy of activation.

A, if i am wrong correct me
