Calculate the standard free enegry chang...

Calculate the standard free enegry change for the reaction:
`Zn + Cu^(2+)(aq) rarr Cu+Zn^(2+) (aq), E^(Theta) = 1.20V`

Text Solution

Verified by Experts

We know that
`DeltaG^(Theta) =- nFE^(Theta)`
`Zn +Cu^(2+) rarr Cu +Zn^(2+)`
`n =2, E = 1.10V, F = 96500C`
`:. DeltaG^(Theta) =- 2 xx (96500C) xx (1.10V)`
`=- 212300 J =- 212.3 kJ ( :' CV = J)`
