Identify the factor from the following that does not affect electrolytic conductance of a solution.

When a solution of an electrolyte is heated,the conductance of the solution:

The equivalent conductance of a monobasic acid at infinite dilution is $348 \, \Omega^{-1} \, cm^2 \, eq^{-1}$. If the resistivity of the solution containing $15 \, g$ of acid (molar mass $49 \, g \, mol^{-1}$) in $1 \, L$ is $18.5 \, \Omega \, cm$,what is the degree of dissociation of the acid? .............. $\%$

Molar conductances of $BaCl_2, H_2SO_4$ and $HCl$ at infinite dilutions are $x_1, x_2$ and $x_3$ respectively. Equivalent conductance of $BaSO_4$ at infinite dilution will be

The limiting molar conductivities of the given electrolytes at $298 \ K$ follow the order: $\lambda^{\circ}_{(K^{+})} = 73.5, \lambda^{\circ}_{(Cl^{-})} = 76.3, \lambda^{\circ}_{(Ca^{2+})} = 119.0, \lambda^{\circ}_{(SO_{4}^{2-})} = 160.0 \ S \ cm^{2} \ mol^{-1}$.

Kohlrausch's law states that at
