The standard electrode potential ( E^(@)...

The standard electrode potential `( E^(@) )` for Daniel cell is `+ 1.1`V. Calculate, the `Delta G^(@)` for the reaction, `Zn(s) + Cu^(2+) ( aq) rarr Zn^(2+) ( aq) + Cu(s)`
`1F = 96500 C "mol"^(-1))`

Text Solution

Verified by Experts

`Zn(s) + Cu^(2+) ( aq) rarr Zn^(2+) ( aq) + Cu(s)`
`E^(@) = 96500 C "mol"^(-1), n =2`
`Delta G^(@) = -n FE^(@) = - 2 xx 96500xx1.1`
`- 212300 J "mol"^(-1)`
