Given : Cell is constructed using standard half cells, 1) Sn2+ | Sn Eo = -0.140 V 2) Cr3+ | Cr Eo = -740 V Since the reduction potential of Sn half cell is more than Cr half cell. Hence the reduction cell will be Sn cell and oxidation cell will be Cr cell. Since oxidation reaction takes place at anode. Hence the anode reaction is => Cr (s) ------> Cr3+ (aq) + 3 e- Since reduction reaction takes place at cathode. Hence the cathode reaction is => Sn2+ (aq) + 2 e- ------> Sn (s) Multiplying the anode reaction with 2 and cathode reaction with 3 and adding them to get overall spontaneous cell reaction by cancelling 6 electrons as, => 3 Sn2+ (aq) + 2 Cr (s) ------> 2 Cr3+ (aq) + 3 Sn (s) The cell voltage is given by, => Cell voltage = Eo of reduction cell - Eo of oxidation cell = -140 - (-0.740) = 0.600 V.
