E cell

[Emma Scholes 1L]

What is the difference between E cell and E^o ?

[Manya Bali 4E]

E^o is the standard reduction potential. It is the reduction potential calculated at a 1 M solution or at 1 atm and at 25 degrees Celsius.

E is the cell potential, and it can change based on concentrations of product/reactant, temperature, and other nonstandard conditions.

The equation that relates these values is the Nernst equation, which is E = E^o - (RT/nF)lnQ

[Bruce Chen 2H]

E^o is the standard reduction potential, which is essentially the cell potential at STP under ideal conditions.

E is the cell potential that changes based on the "nonstandard" conditions.

[Casandra]

E^o is the standard reduction potential, which means under standard conditions: 1atm, 1M, and at 25 degrees Celsius
E is the cell potential, which changes.

[Niveda_B_3I]

E^o is the standard reduction potential, or basically how badly the molecule wants to be reduced (positive means it wants to be reduced more, negative means it wants to be oxidized more). Ecell basically refers to the total standard reduction potential of the cell with E^o of the cathode - E^o of the anode

[Calvin Patel 2H]

E^o cell is used when under standard conditions. E cell is under "nonstandard" conditions.
