Calculate the standard Gibbs energy for ...

Calculate the standard Gibbs energy for the cell :
`Zn(s)+Zn^(2+)(aq)||Cu^(2+)(aq)|Cu(s)`
`E_((Zn^(2+)//Zn)^(@))=-0.76V,E_((Cu^(2+)//Cu))^(@)=0.34V`, `F=96500 C`.

Text Solution

Verified by Experts

At anode, `Zn rarr Zn^(2+) + 2e^(-)`
At cathode,
`ul(Cu^(2+) + 2e^(-) rarr Cu)`
`ul(Zn+ Cu^(2+) rarr Zn^(2+) + Cu)`
`Delta G^(@)= -n epsi^(@)F`
`=-2(1,1) (96500)`
`= -212300J mol^(-1)`
`= -212.3kJ mol^(-1)`
