: The silver electrode has higher reduction potential. The resulting galvanic cell is Cu(s)|Cu(aq)2+||Ag(aq)+|Ag

Q. Consider the following half cell reactions: $C u^{2 +} + 2 e^{-} = C u$ $E_{C u^{2 +} / C u}^{o} = 0.34 V$ $A g^{+} + e^{-} = A g$ $E_{A g^{+} / A g}^{o} = 0.80 V$ Which one of the following is true?

copper can displace silver from $A g N O_{3}$ solution

silver can displace copper from $C u (N O_{3})_{2}$ solution

silver is more reactive than copper

$C u^{2 +} / C u$ and $A g^{+} / A g$ with positive $E^{\circ}$ values cannot be coupled to form a Galvanic cell

: The silver electrode has higher reduction potential. The resulting galvanic cell is $C u_{(s)} ∣ C u_{(a q)}^{2 +} ∣∣ A g_{(a q)}^{+} ∣ A g$
