(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 ofAg will be formed?
