The standard electrode potential for Daniel cell is 1.1 volt. What is the standard Gibbs energy for the reaction ?

A

212.3 kJ `"mol"^(-1)`

B

`-212.3 "kJ mol"^(-1)`

C

`106.15 "kJ mol"^(-1)`

D

`-106.15 "kJ mol"^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
`DeltaG^(@)= - nFE^(@)`
`= - 2xx96500xx1.1`
`= -212300 J` or `= -212.3 "kJ mol"^(-1)`.
