What is ∆G° for a redox reaction where 6 moles of electrons are transferred and E° =-4.20 V? (F = 96,500 J/(V･mol))

Answer 1

∆Gº = -nFEºcell

∆Gº = -(6)(96,500)(-4.20)

∆Gº = 2,431,800 J/mol = 2432 kJ/mol

(note: Eºcell is negative meaning non spontaneous and ∆Gº is positive, also agreeing with the non spontaneous nature of the reaction)
