The value of `DeltaG^(@)` in the Daniell cell has been found to be -212.3 kJ at `25^(@)C`. Calculate equilibrium constant for the reaction.

Text Solution

Verified by Experts

`DeltaG^(@) = -n F E^(@) =- (2) xx (96500 C) xx 1.23 V = -237.390 kJ`
Thermodynamic efficiency , `eta = (DG)/(DH) xx 100`
`= (-237.390)/(-285.8) xx 100 = 83 %`
