Question

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 "`]

Answer 1

Correct Answer - `-523.03 kJ`
`n=2,F=96500" C",E_(cell)^(@)=2.71" V"`
`DeltaG^(@)=(-2)(2.71" V")xx(96500" C")=-525300" CV"=-525300" J"=-523.03" kJ"`
