Dear Student,
Correct answer is b
First calculate the delta G change for the given reaction
Ag+ +Cl- gives AgCl
G change for the reaction is -58KJ/mol (on solving products – reaction)
Use Delta G=-nFE
Solve E
which will come out to be 0.6 V

Hello student,
the answer goes like
∆G of the reaction can be written as ∆G(products)-∆G(reactants)
and∆G=-nfE here n is the number electrons transferred i.e.,1 here
and F= 96500C
solvin for the∆G(reaction)=-58kj
and we get the answer E=0.6V
