    (i) When emf is positive, the reaction is feasible.
    Eo? cell = Eo? Fe? −Eo? I2? =0.77−0.54=0.23V
    Reaction is feasible.


    (ii) Eo? cell? =Eo? Ag? −Eo? Cu? =0.80−0.34=0.46V
    Reaction is feasible.


    (iii) Eo? cell? =Eo? Fe? −Eo? Cu? =0.77−0.34 =0.43 V
    Reaction is feasible.


    (iv) Eo? cell? =Eo? Fe? −Eo? Ag? =0.77−0.80=−0.03 V
    Reaction is not feasible.


    (v) Eo? cell? =Eo? Br2? ? −EFe? =1.09−0.77=0.32 V 
    Reaction is feasible.
