The standard electrode potential for Daniell cell is 1.1V. Calculate the standard Gibbs energy for the reaction Zn_((s))+Cu_((aq))^(2+) to Zn_((aq))^(2+)+Cu_((s))

Answer»

Solution :REACTION: `Zn_((s))+Cu_((aq))^(2+) to Zn_((aq))^(2+)+Cu_((s))`
Where, `n=2,E_(cell)^(Theta)=1.1V,F=96487" C "mol^(-1)`
`Delta_(r)G^(Theta)=-nFE_(cell)^(Theta)`
`=-(2)(96487" C "mol^(-1))(1.1V)`
`=-212271.4" C "V" "mol^(-1)`
`=-212271.4J" " mol^(-1)`
`=-212.271" K "J" "mol^(-1)`
