A)

Solution :

The E∘Ag+/Ag in more positive . So, Silver -silver ion electrode will form cathode , whereas Cu2+/Cu electrode will act as the anode .

The resulting electrode reaction are ,

Anode : Cu→Cu2++2e−

Cathode Ag++e−→Ag]×2

______________________________

Net cell reaction : Cu+2Ag+→Cu2++2Ag

Eanode=+0.34V

Ecathode=+0.80V

__________________________________

E∘cell=0.80V−0.34V=0.46V

The cell emf is given by the equation,

Ecell=(Ecathode−Eanode)−0.05916log[Cu2+][Ag+]

0.422V=0.46V−0.05912log0.1[Ag+]2

log0.1[Ag+]2=(0.46V=0.422V)×20.0591

=1.286

0.1[Ag+]2=autilog(1.286)=19.32

[Ag+]=(0.119.32)3/2
