For the reduction of silver ions with copper metal, the standard cell potential was found to be +0.46V at `25 ^ (@)C` the value of the standard Gibb's energy , `DeltaG^(@)` will be

A

`-98.0kJ`

B

`89.0 kJ`

C

`-89.0J`

D

`44.5kJ`.

Text Solution

Verified by Experts

The correct Answer is:
C
`Cu+2Ag^(+)rarrCu^(2+)+2Ag,E_("cell")^(@)=0.46V`
`DeltaG^(@)=nF^(@)E=-2xx96500xx0.46J`
`=-88780J=-89kJ`
