reactivity Questions

At $298\text{K}$, the standard electrode potentials of ${\text{Cu}}^{2+}/\text{Cu},{\text{Zn}}^{2+}/\text{Zn},{\text{Fe}}^{2+}/\text{Fe}$ and ${\text{Ag}}^{+}/\text{Ag}$ are $0.34\text{V},-0.76\text{V},-0.44\text{V}$ and $0.80\text{V}$, respectively. On the basis of standard electrode potential, predict which of the following reaction cannot occur?
