Answer #1

We know the formula, ∆G° = - nFE°

Where, ∆G° is the change in free energy at STP

n is number of electron transferred

F is faraday constant

E° is redox potential of a cell at STP

Given, n=6 mol, F= 96500 J/(V-mol) , E°= -4.20 V

So, ∆G°= -(6 mol) ×( 96500J/(V-mol))× (-4.20V)

= 2,431,800 J (ans)
