Bromine half cell
WebMay 7, 2024 · Conversely, any species on the right side of a half-reaction will spontaneously reduce any species on the left side of another half-reaction that lies above it in the table. We can use these generalizations to predict the spontaneity of a wide variety of redox reactions (E° cell > 0), as illustrated in Example \(\PageIndex{1}\).
