What is the effect of dilution on the equivalent conductivity of a strong electrolyte?

The conductivity of $0.001 \ M$ acetic acid at a certain temperature is $5.07 \times 10^{-5} \ S \ cm^{-1}$. If $\wedge_m^0$ of acetic acid at the same temperature is $390 \ S \ cm^2 \ mol^{-1}$,the dissociation constant of acetic acid at that temperature is:

At a particular temperature, the ratio of equivalent conductance to specific conductance of a $0.01 \ N$ $NaCl$ solution is

Which of the following expressions correctly represents the equivalent conductance at infinite dilution of $Al_2(SO_4)_3$? Given that $\Lambda_{Al^{3+}}^o$ and $\Lambda_{SO_4^{2-}}^o$ are the equivalent conductances at infinite dilution of the respective ions.

The ionic conductance of the following cations in a given concentration is in the order:

The unit of molar conductivity is
