           (ii)1 mol of  FeO\ to\ Fe_{2}O_{3} ?

Answers (1)

The oxidation equation for the given reaction will be :-  

                                                       Fe^{+2}\ \rightarrow\ Fe^{+3}\ +\ e^-

So for oxidation of  1 mol Fe^{+2} charge required   = 1F

                                                                              = 96500\ C
