The correct order of E_(M^(2+) //M)^(@) values with negative sign for – InterviewSolution

1.	The correct order of E_(M^(2+) //M)^(@) values with negative sign for the four successiveelements Cr, Mn, Fe and Co is
Answer» `Fe GT Mn gt Cr gt Co` `Cr gt Mn gt Fe gt Co` `Mn gt Cr gt Fe gt Co` `Cr gt Fe gt Mn gt Co` Solution :`E^(@)` values for `Mn^(2+) //Mn` with NEGATIVE SIGNS are `:` `Cr = - 0.91 V,Mn= -1.18V, Fe = - 0.44 V, Co= - 0.28 V` THUS, the order is `Mn gt Cr gtFe gt Co`
