Question

Under standard conditions, the Gibbs free energy of the reactants G,std(reactants) in a redox reaction in aqueous solution is 360.65 kJ and the Gibbs free energy of the products G,std(products) is 158.14 kJ. The number of moles, n, of electrons transferred in the redox reaction is 2. Calculate the standard cell potential E,zero for a voltaic cell utilizing this reaction at 25degC. Enter your answer as a number of volts with two decimal places.

Answer 1

dGrxn = dGproducts - dGreactants
Then dGrxn = -nFEo
Solve for Eo.
