Write the Nernst equation for following cell : Sn(s)|Sn^(2+)|H^(+)|H_(2)(g)(1"bar")|Pt(s)

Answer»

Solution :The cell REACTION is :
`SN+2H^(+)toSn^(2+)+H_(2)`
n=2
`E_("cell")=E_("cell")^(@)+(2.303RT)/(nF)log""([H^(+)]^(2))/([Sn^(2+)])`
or `E_("cell")=E_("cell")^(@)+(0.0591)/(n)log""([H^(+)]^(2))/((Sn^(2+)))`
