(a) Calculate `DeltaG_(f)^(@)` of the following reaction
`Ag^(+)(aq) +CI^(-)(aq) rarr AgCI(s)`
Given: `DeltaG_(f)^(@) (agCI) =- 109 kJ//"mole", DeltaG_(f)^(@)(CI^(-)) =- 129 kJ//"mole", DeltaG_(f)^(@) (Ag^(+)) = 77 kJ//"mole"`
Represent the above reaction in form of a cell
Calculte `E^(@)` of the cell. Find `log_(10).K_(sp)` of `AgCI`
(b) `6.539 xx 10^(-2)g` of metallic `Zn(amu = 65.39)` was added to `100ml` of saturated solution of `AgCI`.
Calculate `log_(10).([Z^(2+)])/([Ag^(+)]^(2))` given that
`Ag^(+) +e^(-) rarr Ag E^(@) = 0.80V, Zn^(2+) +2e^(-) rarr Zn E^(@) =- 0.76V`
also find how many moles of `Ag` will be formed?

Answer

`(a) E^(@) = 0.59 V, log_(10) K_(sp) =- 10` (b) `52.8, 10^(-6)` moles
