Which statement best describes the significance of a common intermediate in a pair of coupled chemical reactions?
(a) It lowers the activation energy of both reactions by providing an alternative pathway, acting like a catalyst for each.
(b) It ensures the two reactions occur in separate vessels without mixing reagents.
(c) It links the reactions so their individual ΔG∘ values sum, determining the overall spontaneity of the combined process.
(d) It allows the unfavorable reaction to proceed because the intermediate blocks the reverse reaction from occurring.
