Metallic and ionic conductivity depends on which factors?

The correct order of equivalent conductance of $LiCl$, $NaCl$ and $KCl$ at infinite dilution is

The resistance of $1 \, M$ acetic acid is $250 \, \Omega$. The cell constant of the conductivity cell is $1.15 \, \text{cm}^{-1}$. What is the equivalent conductivity (in $\Omega^{-1} \, \text{cm}^2 \, \text{equiv}^{-1}$) of $1 \, N$ acetic acid?

The graphical variation of molar conductivity $(\Lambda_m)$ against the square root of molar concentration $(\sqrt{c})$ for a certain electrolyte '$X$' is linear with an intercept on the y-axis. Identify '$X$' from the following.

The resistance of a $0.5 \, M$ solution of an electrolyte in a cell was found to be $50 \, \Omega$. If the electrodes in the cell are $2.2 \, cm$ apart and have an area of $4.4 \, cm^2$,then the molar conductivity (in $S \, m^2 \, mol^{-1}$) of the solution is:

The equivalent conductance of $NaCl$ at concentration $C$ and at infinite dilution are $\lambda_C$ and $\lambda_{\infty}$ respectively. The correct relationship between $\lambda_C$ and $\lambda_{\infty}$ is given as: (Where the constant $B$ is positive)
