Why $\mathrm{E}^{\circ}$ values for $\mathrm{Mn}, \mathrm{Ni}$ and $\mathrm{Zn}$ are more negative than expected?
The more negative $\mathrm{E}^{\circ}$ values for $\mathrm{Mn}^{2+}$ and $\mathrm{Zn}^{2+}$ is due to half filled and fully filled configurations respectively. While large negative value of $\mathrm{Ni}^{2+}$ is due to highest negative hydration enthalpy.
