WebThe overall cell potential under standard conditions can be calculated as . E. o cell = E. o(red) + Eo (ox) = Eo(cathode) – Eo(anode) where E. o (cathode) and E. o (anode) are the standard reduction potentials for these half-cell reactions. A spontaneous net cell reaction (e, a galvanic cell) would yield a positive value of .g E. o cell. Webcell is the cell potential at standard conditions o E cell is the cell potential at non -standard conditions (what we want) 2. The derivation: • Putting things together: -nFE cell = -nFE° cell +RTlnQ-nFE cell/-nF = -nFE° cell/-nF +RTlnQ/-nF .
