Answer any three of the following questions.
b. Calculate the value of `Delta r G^(0)` at `298K` for the cell reaction `3Mg(s) + 2AI^(+3) to 3Mg^(+) (aq) + 2AI(s)`

Explanation

`E_("cell")^(0) = E_(AI)^(0) - E_("Mg")^(0)`
`E_("cell")^(0) -1.66 - (-2.36)`
`E_("cell")^(0) =0.7`
`Delta G^(0)=nFE_("cell")^(0)`
`DeltaG^(0) = -6 xx 96487 xx 0.7`
`Delta G^(0) =-405245.4`J
`Delta G^(0) =-405.2 "kJ"`
