Show that the electrical work obtainable from a galvanic cell is given by the expression.
$∆ G ° = - nFE °_{cell}$

The cell potential is simply related to the free energy change for the reaction. In an electro chemical cell the system does work by transferring the electric charge through an external circuit. The free energy change

∆ G

is equal to electrical work done.

∆ G = W_{electrical}

For reaction occurring in a electrochemical cell whose electrodes differ in potential by E_cell, the work done when amount of charge nF is transferred is given by

W_{elect} = - {nFE}_{cell}

∴

∆ G = - {nFE}_{cell}

Under standard state conditions
ΔG° = – n FE°_cell.
