(a) The electrode potential for the Daniell cell given below is 1.1 V. Zn(s) |Z_(n)^(2+)(aq)||Cu^(2+)(aq)|Cu(s) Write overall cell reaction and calculate the standard Gibb's energy for the reaction. [ F 96487 c//mol] (b) Mention any two factors which affects the conductivity of electrolytic solution . |

Answer» Solution :(a) `Zn(s) + Cu^(2+)(aq) to Zn^(2+) (aq) + Cu(s)` `Delta G^(0) = nFE_("CELL")^(0)` `DeltaG^(0) = -2 xx 96487 xx 1.1 = 21227//mol " OR " - 212.27 kJ//mol`. (b) (i) The NATURE of the electrolyte (ii) Temperature (III) Concentration of the electrolyte (IV) Size of the ions produced any their solvation (V) The nature of the solvent and its viscosity. |
