Using the standard electrode potentials given in Table 3.1, predict if the reaction between the following is feasible:
(i) Fe3+(aq) and I−(aq)
(ii) Ag+ (aq) and Cu(s)
(iii) Fe3+ (aq) and Br− (aq)
(iv) Ag(s) and Fe3+ (aq)
(v) Br2 (aq) and Fe2+ (aq).
Sincefor the overall reaction is positive, the reaction between Fe3+(aq) and I−(aq) is feasible.
Since for the overall reaction is positive, the reaction between Ag+ (aq) and Cu(s) is feasible.
Since for the overall reaction is negative, the reaction between Fe3+(aq) and Br−(aq) is not feasible.
Since E for the overall reaction is negative, the reaction between Ag (s) and Fe3+(aq) is not feasible.
Since for the overall reaction is positive, the reaction between Br2(aq) and Fe2+(aq) is feasible.
