The potential of the electrochemical cell is 0.03 V.
An electrochemical cell is a cell that produces chemical energy from a spontaneous chemical process. Let us recall that cell potential can be obtained from; Ecell = 0.0592/n log K
The cell equation is;
Sn(s) + ClO2(g) ----> Sn^2+(aq) + ClO^2-(aq)
Hence;
K = (1.60) (1.60)/(0.220)
K = 11.6
Therefore;
Ecell = 0.0592/2 log (11.6)
= 0.03 V
