22. Four successive members of the first row transition elements listed below with atomic numbers. Which one of them is expected to have the highest $E _{M^{3+} / M^{2+}}^{\circ}$ value?
(2013 Main)
(a) $Cr(Z=24)$
(b) $\operatorname{Mn}(Z=25)$
(c) $Fe(Z=26)$
(d) $Co(Z=27)$
Show Answer
Answer:
Correct Answer: 22. (d)
Solution:
SRP value normally increases from left to right in the period of $d$-block elements. Some SRP value are exceptionally higher due to stability of production. e.g.
$ E _{Mn^{3+} / Mn^{2+}}^{0}=+1.57 V ; E _{Co^{3+} / Co^{2+}}^{0}=+1.97 V $
Thus, $E _{M^{3+} / M^{2+}}^{\circ}$ is highest for Co.
