For the cell :-
2Ag + Pt²⁺ \(\text { → }\) 2Ag⁺ + Pt Eº = 0.4 volt
2Ag + F₂ \(\text { → }\) 2Ag⁺ + 2F^– Eº = 2.07 volt
If the potential for the reaction Pt \(\text { → }\) Pt²⁺ + 2e^– is assigned zero. Then

\(\mathrm{E}_{\mathrm{Ag}^{2} / \mathrm{Ag}^{+}}=-0.4 \mathrm{~V}\)
\(\mathrm{E}_{\mathrm{Ag}^{+} / \mathrm{Ag}}^{\circ}=0.4 \mathrm{~V}\)
\(\mathrm{E}_{\mathrm{F}_{2} / \mathrm{F}^{-}}^{\circ}=1.67 \mathrm{~V}\)
\(\mathrm{E}_{\mathrm{F}_{2} / \mathrm{F}^{-}}^{\circ}=2.74 \mathrm{~V}\)

Answer

(C) E _ F _ 2 / F ^ - ^ =1.67 ~V
