Which of the following statements is true for all exergonic reactions?
A) The products have more total energy than the reactants.
B) The reaction proceeds with a net release of free energy.
C) The reaction goes only in a forward direction: all reactants will be converted to products, but no products will be converted to reactants.
D) A net input of energy from the surroundings is required for the reactions to proceed.

Question

Quizplus · Accepted Answer

Exergonic reactions release free energy, meaning that the products have less total energy than the reactants. Thus, choice A is incorrect. Exergonic reactions go in the forward direction and may reach equilibrium, but the reverse reaction is possible under different conditions, so choice C is incorrect. Finally, choice D is incorrect because exergonic reactions release energy, so they do not require an input of energy from the surroundings. Therefore, the only correct option is B, which states that exergonic reactions proceed with a net release of free energy.
