Calculate the standard Gibbs energy change for the redox reaction of Daniel cell .

Answer»

Solution :Cell reaction in Daniel cell is
`Zn+Cu^(2+) AQ) RARR Zn^(2+) (aq) +Cu`
The standard electrode potential, `E_("cell")^(@)`is 1.1 V.
The standard FREE energy change, `DeltaG^(@)= -nFE_("cell")^(@)`
` = - 2xx1.1xx96500=-21.3 "kJ MOL"^(-1)`.
