Which statement about a spontaneous redox reaction is correct?
A.E°cell is positive
B.E°cell is negative
C.E°cell is zero
D.E°cell has no sign convention
Explanation
Core Concept
A spontaneous reaction has ΔG° < 0, and since ΔG° = −nFE°, a positive cell potential is required. The stronger oxidant oxidizes the stronger reductant.
Correct Answer
AE°cell is positive
