If two reactions are coupled, then

Question

Quizplus · Accepted Answer

Coupled reactions involve using the energy released from an exothermic reaction to drive an endothermic reaction. Therefore, option C is correct. Option A is incorrect because the overall process may be reactant or product favored depending on the individual reactions. Option B is incorrect because the product of one reaction can be a reactant or a product of the second reaction. Option D is incorrect because a product-favored reaction does not supply activation energy, it releases Gibbs free energy. Option E is incorrect because the Gibbs free energy released from a product-favored reaction is used to drive the second reaction rather than being released to the surroundings.
