The free energy of an electrochemical cell is given by the equation:
AG = -nFE
Where:
AG = Gibbs Free Energy change
n = moles of electrons
F = Faraday's constant
E = cell voltage
NOTE: Write AG as dG (with no spaces) for the answers below.
In order to solve for the moles of electrons, n, you must multiply both sides of the equation by the
same expression:
AG X=-FE x
The resulting equation is:
n =
