Quizplus · Accepted Answer

To produce silver (Ag), the coupled reaction must have a negative ΔG° value that, when added to the given reaction's ΔG° (11.2 kJ/mol), results in a negative total ΔG°, indicating spontaneity. Only option B, with a ΔG° of -137.2 kJ/mol, meets this criterion, ensuring the overall process is spontaneous.
