Standard electrode potential for Sn^{4 +} / Sn^{2 +} couple is + 0.15 V and that for the Cr^{3 +} / Cr couple is - 0.74 V . These two couples in their standard state are connected to make a cell. The cell potential will be:

A $+ 1.83 V$
B $+ 1.19 V$
C $+ 0.89 V$
D $+ 0.18 V$

Solution & Step-by-step Explanation

For a cell, the couple with higher reduction potential acts as the cathode.Cathode: Sn^{4 +} / Sn^{2 +} (E^{\circ} = 0.15 V)Anode: Cr^{3 +} / Cr (E^{\circ} = - 0.74 V) E_{ce ll}^{\circ} = E_{c a t h o d e}^{\circ} - E_{an o d e}^{\circ} E_{ce ll}^{\circ} = 0.15 - (- 0.74) = 0.15 + 0.74 = + 0.89 V
