A) \[\text{E}_{\text{cell}}^{\text{o}}\]cell should be infinite
B) \[\text{E}_{\text{cell}}^{\text{o}}\]cell should be zero,
C) \[\text{E}_{\text{cell}}^{\text{o}}\] cell should be positive
D) \[\text{E}_{\text{cell}}^{\text{o}}\] cell should be negative
Correct Answer: C
Solution :
Key Idea:\[E_{cell}^{o}=E_{C}^{o}-E_{A}^{o}\] For spontaneous reaction must be positive. If \[E_{cell}^{o}\]is negative or zero, then cell will not work.
