Predict whether the following redox reaction is feasible under the standard conditions or not.
Sn2+(aq) + Cu(s) → Sn(s) + Cu2+(aq)
In the given cell the reduction of Sn 2+ ions takes pace and also the oxidation of copper metal to copper ions takes place.Eo cell is
E°cell = E°cathode - E°anode
E°cell = E° Sn2+ / Sn - E° Cu2+ / Cu
= -0.14 V – ( -0.34) = 0.20V
Δ Go = - nFEo celll
= -2 x 96500 x 0.20 V = -38600 J
