WebThe various electrochemical processes that occur in a voltaic cell occur simultaneously. It is easiest to describe them in the following steps, using the above zinc-copper cell as an example. 1. Zinc atoms from the zinc electrode are oxidized to zinc ions. WebThis is because the copper is more electronegative than the zinc. The cell potential for this reaction is +1.10, since copper is being reduced and zinc is being oxidized, and if you plug this into the free energy equation for a cell ,ΔG= −n× F × EMF, you get ΔG= −2e-× (9.64 x 10^4 F) × (+1.10V) = -212 kJ.
