In the cell,PtsH2g, 1bar HCl aqAgClsAgsPts,the cell potential is0.92 Vwhen a10-6molarHClsolution is used. The standard electrode potential ofAg|AgCl|Cl-electrode is:

(Given,2.303RTF=0.06 Vat298 K)

Options:

Answer:
B
Solution:

A:12H2gH+ aq.+e-; Eo=0.0 V
C :AgCl s+e-Ag s+Cl-; Eo=xV
Ecell=Ecello-0.061logH+Cl-
0.92=x-0.061log10-12
0.92=x+0.72
x=0.92-0.72
=0.2V
