Consider the following `E^(@)` values `E^(@)` values `E_(Fe^(3+)//Fe^(2+))^(@)= 0.77v` , `E_(Sn^(2+)//Sn)^(@) = -0.14` under standard condition the potential for the reaction `Sn_(s)+ 2Fe^(3+)(aq)rightarrow 2Fe^(2+)(aq) + Sn^(2+) (aq)` is :

A

0.91 V

B

1.40V

C

1.68V

D

0.63V

Text Solution

Verified by Experts

The correct Answer is:
A
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
