Consider the following E^(@) values E^(@)(Fe^(3+)|Fe^(2+))=+0.77V,E^(@)(Sn^(2+)|Sn)=-0.14Vunder standard conditions , the potemtial for the reaction : Sn(s)+2Fe^(3+)(aq)to2Fe^(2+)(aq)+Sn^(2+)(aq)is

Answer»

0.19 V
0.140 V
1.68 V
0.63 V

Solution :`E_("CELL")^(@)=E^(@)(FE^(3+)|Fe^(2+))-E^(@)(SN^(2+)|Sn)`
`=0.77-(-0.14)=+0.91V`
