Using the standard electrode potential, ...

Using the standard electrode potential, find out the pair between which redox reaction is not feasible. `E^(@)` values : `Fe^(3+)//Fe^(2+)=+0.77, I_(2)//I^(-)=+0.54 V`
`Cu^(2+)//Cu= + 0.34 V, Ag^(+)//Ag= +0.80 V`

A

`Fe^(3+) and I^(-)`

B

`Ag^(+) and Cu`

C

`Fe^(3+) and Cu `

D

`Ag and Fe^(3+)`

Text Solution

Verified by Experts

Ag cannot reduce `Fe^(3+)` since its `e^(@)` value is more
