Nernst equation for cell potential in case of Zn-Cu cell is given by

Answer»

`E_("CELL") =E_("cell")^(@) +(RT)/(2F) ln ([Zn^(2+)])/([Cu^(2+)])`
`E_("cell") =E_("cell")^(@) -(RT)/(2F) ln ([Zn^(2+)])/([Cu^(2+)])`
`E_("cell") = E_("cell")^(@) -(RT)/(2F) ln ([Cu^(2+)])/([Zn^(2+)])`
`E_("cell") =E_("cell")^(@) -(RT)/(2T) log ([Zn^(2+)])/([Cu^(2+)])`
