Statement 1 : E0  for  Mn3+ /Mn2+ is more positive than Cr3+/Cr2+.Statement 2 : The third ionisation energy of Mn is larger than that of Cr.

It is known that the value of E0 becomes more negative down the series. As the chromium is present below in electrochemical series than Mn, so Mn has more positive E0 value than Cr.Mn → 3d54s2  ;                      Mn2+→  3d54s0Cr→3d54s1    ;      Cr2+→3d44s0For elimination of one electron from Mn2+, more energy is required due to its stable configuration. That is why third Ionization energy of Mn is larger than Cr.
