The standard reduction potentialfor Fe^(2+)//Fe and Sn^(2+)//Sn electrodesare -0.44 and -0.14 Vrespecitvely for the cell reaction Fe^(2+)+SnrarrFe+Sn^(2+) the standard emf is

Answer»

`+0.30 V`
`+0.58 V`
`+0.58 V`
`-0.30 V`

Solution :`E_("CELL")^(@)=E_("oxi")^(@)("Sn")+ E_("RED")^(@)(Fe)`
`=+0.14 +(-0.44) =- 0.30 V`
