(a) Calculate `/_\G_"f"^0` of the following reaction
`Ag^+(aq)+Cl^(-)(aq) rarr AgCl(s)`
given `/_\G_"f"^0` (AgCl) =` -109kJ//"mole"`,
`_"f"/_\G^0(Cl^-)=-129kJ//"mole"`
`_"f"/_\G^0(Ag^+)=77kJ//"mole"`
represent the above reaction in from of a cell. Calculate `E^0` of the cell. Find `log_10K_(SP)` of AgCl
(b) `6.539xx10^-2` g of metallic Zn (amu = 65.39) was added to 100 ml of saturated solution of AgCl.
Calculate `log_10([[Zn^(2+)]]/[Ag^+]^2)` ,given that
`Ag^++e^(-) rarr AgE^0=0.80V` , `Zn^(2+)+2e^(-) rarr ZnE^0=-0.76V`
Also find how many moles of Ag will be formed?

Answer

`(a)E^0=0.59V,log_10K_(sp)=-10,(b)52.8,10^(-6)"moles"`
