For the first row transition metals the Eo values are: Eo V Cr Mn Fe Co Ni Cu (M2+/M) –1.18 – 0.91 –1.18 – 0.44 – 0.28 – 0.25 +0.34 Explain the irregularity in the above values

The E
(M2+/M) values are not regular which can be explained from
the irregular variation of ionisation enthalpies ( delta H1 + delta H2 ) and also
the sublimation enthalpies which are relatively much less for
manganese and vanadium.
