The standard emf of Deniell cell is 1.1 ...

The standard emf of Deniell cell is `1.1` V. Calculate the standard Gibbs energy for the cell reactions:
`Zn_((s))+Cu_((aq))^(2+)to Zn _((aq))^(2+)+Cu_((s))`

Text Solution

Verified by Experts

`Delta_(r) G^(ө) = - nFE_("(Cell)")^(ө)` n is the above equation is 2, F = 96487 C `mol^(-1)` and `E_("(Cell)")^(ө) = 1.1 V`
Therefore , `Delta_(R) G^(ө) = - 2 xx 1.1V xx 96487 C mol^(-1)`
` = -21227 J mol^(-1)`
