Which conductance shows a decrease in its value upon increasing the temperature of an electrolyte solution?

Calculate the cell constant of a conductivity cell containing $0.01 \ M \ AgNO_3$ solution having a resistance of $1440 \ \Omega$ and a conductivity of $0.001262 \ \Omega^{-1} \ cm^{-1}$. (in $cm^{-1}$)

Molar ionic conductivities of a divalent cation and a divalent anion are $57 \ S \ cm^2 \ mol^{-1}$ and $73 \ S \ cm^2 \ mol^{-1}$ respectively. The molar conductivity of a solution of an electrolyte containing these ions will be:

The conductivity of $0.20 \, M$ solution of $KCl$ at $298 \, K$ is $0.0248 \, S \, cm^{-1}$. Calculate its molar conductivity.

Calculate the molar conductivity for the following two solutions and determine which has the maximum value:
$(1)$ $A$ solution with conductivity $\kappa = 2 \times 10^{-2} \, \Omega^{-1} \, cm^{-1}$ and molarity $M = 0.08 \, M$.
$(2)$ $A$ solution with resistivity $\rho = 50 \, \Omega \, cm$ and molarity $M = 0.1 \, M$.

The ionic conductivity of $Ba^{2+}$ and $Cl^{-}$ at infinite dilution are $127$ and $76 \ ohm^{-1} cm^2 eq^{-1}$ respectively. The equivalent conductivity of $BaCl_2$ at infinite dilution (in $ohm^{-1} cm^2 eq^{-1}$) would be $:-$
