How do you calculate electrochemical cell potential?

2013/12/22Warning! VERY long answer! You can calculate the cell potential for an electrochemical cell from the half-reactions and the operating conditions. The first step is to determine the cell potential at its standard state — concentrations of 1 mol/L and pressures of 1 atm at 25C. The procedure is: Write the oxidation and reduction half-reactions for the cell.

Electrochemical Reactions

Voltaic Cells Electrochemical cells that use an oxidation-reduction reaction to generate an electric current are known as galvanic or voltaic cells.Because the potential of these cells to do work by driving an electric current through a wire is measured in units of volts, we will refer to the cells that generate this potential from now on as voltaic cells.
