WebJun 22, 2024 · The Pb reaction in the table and in the cell are in the same direction (i.e. reduction). This will always be the case for the cathode, because the table lists reduction … WebJul 19, 2024 · We now solve the cell potential equation using the reduction potentials given in the table above. E cell ∘ = E cathode ∘ − E anode ∘ = E Fe 3 + / Fe 2 + ∘ − E Zn 2 + / Zn ∘ = ( 0.77 V) − ( − 0.76 V) = 1.53 V. This galvanic cell produces very little voltage when using these two half-reactions.
