E° = –2.93 V. L et's calculate the potential generated in by a cell constructed from standard Zr and I 2 electrodes: From the table, we write a balanced reduction half-reaction for each electrode and copy down the reduction potentials: 2e – + I 2 (s) 2 I – (aq) E° = 0.54 V. 4e – + Zr 4+ (aq) Zr (s) E° = –1.53 V. E° cell: Standard Cell Potential E° cell is the electromotive force (also called cell voltage or cell potential) between two half-cells. The greater the E° cell of a reaction the greater the driving force of electrons through the system, the more likely the reaction will proceed (more spontaneous). E° cell is measured in volts (V).
