The `E_(cell)` for a given cell is `1.2346` and `1.2340V` at `300K ` and `310K`, respectively. Calculate the change in entropy during the cell reaction if the redox change involves three electrons.

A

`-17.37 J K^(-1)`

B

`+17.37 J K ^(-1)`

C

`173.7J K^(-1)`

D

`5.79 J K^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
a

By `DeltaS=(DeltaH-DeltaG)/(T),`
`DeltaH=-nF[E-T((delE)/(delT))_(P)]` and `DeltaG=-nEF`
`DeltaS=-nF((delE)/(delT))_(p)=3xx96500xx(-(0.0006)/(10))`
`=-17.37 J K^(-1)`
