How do you calculate electrochemical cell potential ...

Dec 22, 2013 · Warning! 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 25°C. The procedure is: Write the oxidation and reduction half-reactions for the cell.

Standard Electrode Potentials - HyperPhysics Concepts

Standard Electrode Potentials. In an electrochemical cell, an electric potential is created between two dissimilar metals. This potential is a measure of the energy per unit charge which is available from the oxidation/reduction reactions to drive the reaction. It is customary to visualize the cell reaction in terms of two half-reactions, an oxidation half-reaction and a reduction half-reaction.
