Question

Select the correct statements about $\mathrm{M}^{2+} / \mathrm{M}$ standard electrode potentials of the first transition series\ I) The general trend towards the less negative $\mathrm{E}^{0}$ values along the series is due to the general increase in the sum of $\mathrm{IE}_{1}$ and $\mathrm{IE}_{2}$\ II) Cu is the only metal with positive $\mathrm{E}^{0}$ value\ III) The $\mathrm{E}^{0}$ values for $\mathrm{Mn}, \mathrm{Ni}$ and Zn are more negative than expected.\
