Consider the following E^(o) values E_(Fe^(3+)//Fe^(2+))^(o)=+0.77V E_(Sn^(2+)//Sn)^(o)=-0.14V Under standard conditions the potential for the reactio Sn_((s))+2Fe_((aq))^(3+)to2Fe_((aq))^(2+)+Sn_((aq))^(2+) is

Answer»

0.91 V
1.40V
1.68V
0.63V

Solution :For `Sn_((s))+2Fe_((aq))^(3+)to2Fe_((aq))^(2+)+Sn_((aq))^(2+)`
`E_(cell)^(o)=E_(SN//Sn^(2+))^(o)+E_(Fe^(3+)//Fe^(2+))^(o)=(0.14)+(0.77)`
`E_(cell)=0.91` VOLTS
