Vedclass · Answer

(A) The cell potential $E^o_{cell}$ is calculated as $E^o_{cell} = E^o_{cathode} - E^o_{anode}$.To obtain the maximum potential,we must choose the half-cell with the highest reduction potential as the cathode and the half-cell with the lowest reduction potential as the anode.Comparing the given values:$E^o_{(i)} = -0.24 \ V$$E^o_{(ii)} = +1.25 \ V$ (Highest)$E^o_{(iii)} = -1.25 \ V$ (Lowest)$E^o_{(iv)} = +0.68 \ V$Thus,the cathode is $(ii)$ and the anode is $(iii)$.$E^o_{cell} = 1.25 - (-1.25) = 2.50 \ V$.
