(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 .

Text Solution

Verified by Experts

(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.
