Calculate Delta(r)G^(@) for the reaction...

Calculate `Delta_(r)G^(@)` for the reaction :
`Mg(s)+Cu^(2+)(aq) to Mg^(2+)(aq)+Cu(s)`
[Given `E_(cell)^(@)=+2.71" V ", 1F=96500" C "`]

Text Solution

Verified by Experts

`Delta_(r) G^(@) = - n F E_(cell)^(@)`
`E_(cell)^(@) = 2.71 V , 1 F = 96500 C mol^(-1) ,n = 2`
`Delta_(r) G^(@) = - 2 xx 96500 C mol^(-1) xx 2.71 V `
`= - 523030 J mol^(-1) " " (1 CV = 1 J)`
or `= - 523.030 kJ mol^(-1)`
