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.

In a galvanic cell, a spontaneous redox reaction occurs. However the reactants are separated such that the transfer of electrons is forced to occur across a wire. The resulting electricity is measured in volts (V) and is the sum of the potentials of the oxidation and reduction half-reactions: E^o cell = E^o red + E^o ox By reversing the reduction half-reactions, you get the corresponding oxidation half-reaction, for which E^o ox has the opposite sign of E^o red You can...
