If a standard cell potential is at 25 , is the redox reaction of the cell spontaneous?
| Yes, a redox reaction with a positive standard cell potential is spontaneous under standard conditions. |
| No, a redox reaction with a positive standard cell potential is not spontaneous under standard conditions. |
| No, a redox reaction will not take place at all. |
For reaction to be spontaneous under standard condition, Eo should be positive.
Here Eo is positive.
So, the reaction is spontaneous
Answer: Yes, a redox reaction with a positive standard cell potential is spontaneous under standard conditions.
