The limiting molar conductivity of \(AgI\),
\(Λ^0_m(AgI) = Λ^0_m(NaI)+Λ^0_m(AgNO_3)-Λ^0m(NaNO_3)\)
\(Λ^0_m(AgI) = 12.7 + 13.3 – 12.0\)
\(Λ^0_m(AgI) = 26 – 12\)
\(Λ^0_m(AgI) =14\ mS m^2 mol^{–1}\)
So, the answer is \(14\ mS m^2 mol^{–1}\).
For the given cell: \[ {Fe}^{2+}(aq) + {Ag}^+(aq) \to {Fe}^{3+}(aq) + {Ag}(s) \] The standard cell potential of the above reaction is given. The standard reduction potentials are given as: \[ {Ag}^+ + e^- \to {Ag} \quad E^\circ = x \, {V} \] \[ {Fe}^{2+} + 2e^- \to {Fe} \quad E^\circ = y \, {V} \] \[ {Fe}^{3+} + 3e^- \to {Fe} \quad E^\circ = z \, {V} \] The correct answer is:
