To calculate the equilibrium constant for an electrochemical cell we need to know: the standard state potential for a cell. the half-reactions involved.
...
Zn(s) Zn2+(aq) + 2 e- Eooxidiation = + 0.762 volts
Cu2+(aq) + 2 e- Cu(s) Eoreduction = + 0.339 volts
Zn(s) + Cu2+(aq) Zn2+(aq) + Cu(s) Eocell = + 1.101 volts
The cell potential, Ecell, is the measure of the potential difference between two half cells in an electrochemical cell. The potential difference is caused by the ability of electrons to flow from one half cell to the other. ... Conversely, during reduction, the substance gains electrons and becomes negatively charged.
