MCQ
A negative $e.m.f.$ for a cell represents
- AElectrons will flow through external circuit in reverse direction.
- BThe opposite half cell reaction will take place spontaneously.
- CThe given reaction will not be spontaneous
- ✓All of the above
✓
Answer
Correct option: D.
All of the above
d
$EMF$ of the cell is always the difference in higher reduction potential and lower reduction potential. If the $EMF$ is negative, it indicates that the electron flow is in the reverse direction, both the reactions are not as spontaneous as they should be.
