For the first row transition metals the ${E^\Theta }$ values are:
${E^\Theta }$ | $V$ | $Cr$ | $Mn$ | $Fe$ | $Co$ | $Ni$ | $Cu$ |
$\left( {{M^{2 + }}/M} \right)$ | $-1.18$ | $-0.91$ | $-1.18$ | $-0.44$ | $-0.28$ | $-0.25$ | $+0.35$ |
Explain the irregularity in the above values.
The catalytic activity of the transition metals and their compounds is ascribed to their
