E^(@) values for Fe^(3+)//Fe^(2+) and Ag...

`E^(@)` values for `Fe^(3+)//Fe^(2+)` and `Ag^(+)//Ag` are 0.771 V and 0.8 respectively. Is the reaction,
`Fe^(3+)+Ag to Fe^(2+)+Ag^(+)`
Spontaneous or not ? Give reason also.

Text Solution

Verified by Experts

`Fe^(3+)+AgrarrFe^(2+)+Ag^(+), E_(Fe^(3+)//Fe^(2+))^(@)=0.771V`
`E_(Ag^(+)//Ag)^(@)=0.800V`
This is an non spontaneous reaction `beause` Ag having high reduction potential, so it should act as cathod and get reduced.
