Using the standard electrode potentials | Class 12 Chemistry Chapter Electrochemistry, Electrochemistry NCERT Solutions

Question:

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).

Answer:

Since Eº for the overall reaction is positive, the reaction between Fe3+(aq) and I - (aq) is feasible.

Since Eº for the overall reaction is positive, the reaction between Ag+(aq) and Cu(s) is feasible.

Since Eº for the overall reaction is negative, the reaction between Fe3+(aq) and Br - (aq) is not feasible.

Since Eº 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

If electrode potential is positive, then Gibbs Free Energy is negative meaning the reaction is spontaneous and feasible.
