Consider the following E(0) values, E(...

Consider the following `E_(0)` values,
`E_(Fe^(3+)//F^(2+))^(0)=+0.77V, E_(Sn^(2+)//Sn)^(0)=-0.14V`, the `E_(cell)^(0)` for the reaction,
`Sn_((s))+2Fe_((aq.))^(3+)rarr2F_((aq.))^(2+)+Sn_((aq.))^(2+)` is:

A

`0.63V`

B

`1.40V`

C

`0.91V`

D

`1.68V`

Text Solution

Verified by Experts

The correct Answer is:
C
`E_(cell)^(0)=E_(OP_(Sn//Sn^(2+)))^(0)+E_(RP_(Fe^(3+)//FE^(2+)))^(0)`
`=0.14+0.77=0.91V`
