1.	The standard reduction potentials, E∘, for the half-reactions are as Zn=Zn2++2e, E∘= + 0.76 V and Fe=Fe2++2e, E∘ = + 0.41 V. The e.m.f. for the cell reaction, Fe2++Zn=Zn2++Fe is
Answer» The standard reduction potentials, $E^{\circ}$ , for the half-reactions are as $Z n = Z n^{2 +} + 2 e$ , $E^{\circ}$ = + 0.76 V and $F e = F e^{2 +} + 2 e$ , $E^{\circ}$ = + 0.41 V. The e.m.f. for the cell reaction, $F e^{2 +} + Z n = Z n^{2 +} + F e$ is
