If the temperature coefficient of `EMF `if `-0.125V K^(-1), DeltaS` for the given cell at `25^(@)C` is `:` `Fe|Fe^(2+)(aq)||Cd^(2+)(aq)|Cd`A. `-26.125 k J K^(-1)`B. `-24.125k J K^(-1)`C. `-22.125 kJ K^(-1)`D. `-20.125 k J K^(-1)`

Answer» Correct Answer - b
`n_(cell)=2,((delE)/(deltT))=-0.125 VK ^(-1)`
`DeltaS=nF((delE)/(delT))`
`=2xx96500Cxx-0.125 V K^(-1)`
`=-24125 J K^(-1)`
`=-241.25 kJ K^(-1)`
