Question

In the given reaction,

Copper metal, $Cu(s)$ is oxidised to $C{u}^{2+}(aq)$, while $A{g}^{+}(aq)$ is reduced to silver metal, Ag $(s)$ then the equilibrium greatly lies in favour of

• A. $A{g}^{+}(s)$ and $C{u}^{2+}(aq)$
• B. $A{g}^{+}(aq)$ and $C{u}^{2+}(s)$
• C. $Ag(s)$ and $C{u}^{2+}(aq)$
• D. $C{u}^{2+}(aq)$ and $Ag(s)$

Answer 1

Answer: (D)

Copper being more reactive than silver, can displace silver from its salt solution but opposite is not possible. Thus, equilibrium lies towards right hand side, i.e. in favour of $C{u}^{2+}$ and Ag.
