Calculate the standard Gibbs energy for ...

Calculate the standard Gibbs energy for the cell :
`Zn(s)|Zn^(2+)(aq)||Cd^(2+)(aq)|Cd(s)`
`E_((Zn^(2+)//Zn))^(@)=-0.76V,E_((Cd^(2+)//Cd))^(@)=-0.403V,F=96500C`.

Text Solution

Verified by Experts

`Delta G^(@)= -nE^(@)F`
`=-2(0.357) (96500)`
`= -68901J mol^(-1)`
`= -68901 kJ mol^(-1)`
