Consider the following E0 values: E0Fe3- Fe2- = +0.77V  E0 Sn 2-Sn = -0.14V Under standard conditions the potential for the reaction Sn + 2Fe gives to 2Fe2+ + Sn2+ is 1.      1.68V 2.      1.40V 3.      0.91V 4.      0.63V

Dear Sumanjal,

The correct option is: 3. 0.91V

Solution:

The reduction half cell reactions and E0 values are:

Fe3+(aq) + e- → Fe2+(aq)              E0 = + 0.77 V

Sn2+(aq) + 2e- → Sn(s)                  E0 = - 0.14 V

In the reaction, Sn is being oxidized and so the overall cell potential is:

E0 = [(+0.77) – (-0.14)] V = + 0.91 V
