The standard electrode potential for daniell cell is 1.1 V. calculate the standard gibbs energy for the reaction
`Zn(s)+Cu^(2+)(aq)toZn^(2+)(aq)+Cu(s)`

Text Solution

Verified by Experts

`Delta_(r)G^(c-)=-nFE^(c)._(cell)`
`n` in the above equation is `2,F=96487C mol^(-1) ` and `E^(c-)._(cell)=1.1V.`
`:. Delta_(r)G^(c-)=-2 xx 96487 C mol ^(-1) xx 1.1 V`
`=-21.227 J mol ^(-1)`
`=-21.227 kJ mol^(-1)`
