Calculate the DeltaG^(@) of the followin...

Calculate the `DeltaG^(@)` of the following reaction :-
`Fe^(+2)(aq)+Ag^(+)(aq)toFe^(+2)(aq)+Ag(s)`
`E_(Ag^(+)//Ag)=0.8V" "E_(Fe^(+3)//Fe^(+2))^(0)=0.77V`

A

`-2895 J mol^(-1)`

B

`-3845 J mol^(-1)`

C

`-1874 J mol^(-1)`

D

`-375 J mol^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
A

`E_(cell)^(0)=0.8-0.77=0.03 V`
`DeltaG^(@)=-nFE_(cell)^(@)=-1xx96500xx0.03`
`=-2895 J//mol`
