Ionic Conductance

Q. The specific conductance of $\frac{N}{10}KCl$ solution at ${20}^{\circ }C$ is $0.0212oh{m}^{-1}c{m}^{-1}$ and the resistance of cell containing this solution at ${20}^{\circ }C$ is 55 ohm. The cell constant is

1. 1.166 cm^-1
2. 2.173 cm^-1
3. 3.324 cm^-1
4. 4.616 cm^-1

Q. 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)

1. ${\lambda }_c={\lambda }_{\infty }+\left(B\right)C$
2. ${\lambda }_c={\lambda }_{\infty }-\left(B\right)C$
3. ${\lambda }_c={\lambda }_{\infty }-B\sqrt{C}$
4. ${\lambda }_c={\lambda }_{\infty }+B\sqrt{C}$
