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