For the reduction of silver ions with copper metal, the standard cell potential was foound to be `+0.46 V` at `25^(@) C`. The value of standard Gibbs energy, `DeltaG^(@)` will be `(F = 96,500C mol^(-1))`:

A

`-98.0kJ`

B

`-89.0kJ`

C

`-89.0J`

D

`-44.5kJ`

Text Solution

Verified by Experts

The correct Answer is:
B
`2Ag^(+)+Cuto2Ag+Cu^(2+)`
`n=2`
`DeltaG=-nFE_(cell)`
`DeltaG=-2xx96500xx0.46` joul
`DeltaG=-88.78kJ=-89kJ`.
