If a standard cell potential is E∘cell=+0.85VEcell∘=+0.85V at 25 ∘C∘C, is the redox reaction of the cell spontaneous? 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.
