If the DeltaG^@ of a cell reaction AgCl+...

If the `DeltaG^@` of a cell reaction `AgCl+e^(-)toAg+Cl^(-)` is -21.20 kJ, the standard emf of cell is

A

0.229V

B

0.220V

C

`-0.220V`

D

`-0.110V`

Text Solution

Verified by Experts

The correct Answer is:
B
Given: `DeltaG=-21.20kJ=0.22V`
`becauseDeltaG=-nFE`
`E=(21200)/(1xx96500)=0.2196V=0.22V`
