1.	Using the standard electrode potentials given in the Table-8.1, predict if the reaction between the following is feasible : (a) Fe_((aq))^(3+)andI_((aq))^(-) (b) Ag_((aq))^(+)andCu_((s)) ( c) Fe_((aq))^(3+)andCu_((s)) (d) Ag_((s))andFe_((aq))^(3+) (e) Br_(2(aq))andFe_((aq))^(2+)
Answer» Solution :(a) `Fe_((aq))^(3+)andI_((aq))^(-)` probable REACTION … `2Fe_((aq))^(3+)+2I_((aq))^(-)to2Fe_((aq))^(2+)+I_(2(s))` Value of `E^(@)` is POSITIVE, therefore reaction is possible. (b) `Ag_((aq))^(+)+Cu_((s))` Probable reaction is `2Ag_((aq))^(+3)+Cu_((s))to2Ag_((s))+Cu_((aq))^(+2)` Value of `E^(@)` positive, therefore reaction is possible. ( c) `Fe_((aq))^(+3)+Cu_((s))` posiible reaction between them. Value of `E^(@)` positive therefore reaction is possible. (d) `Ag_((s))+Fe_((aq))^(+3)` possible reaction between them. `E^(@)` is negative so reaction is not possible. (e) `Br_(2(aq))+Fe_((aq))^(+2)` possible reaction between them. `E^(@)` is positive, therefore reaction is possible.
