Consider the liquids and solutions behave ideally.

| $Ion$ | $Z ^{ n +}$ | $Z ^{ P +}$ | $Z ^{ n +}$ | $Z ^{ m +}$ | $Z ^{ m +}$ |
| $\lambda^0\left( S cm ^2 mol ^{-1}\right)$ | $50.0$ | $25.0$ | $100.0$ | $80.0$ | $100.0$ |
$\lambda^0$ is the limiting molar conductivity of ions
The plot of molar conductivity $(4)$ of $Z _{ m } X _{ n } v s c ^{1 / 2}$ is given below.
$\mathrm{A}(\mathrm{g}) \rightarrow 2 \mathrm{~B}(\mathrm{~g})+\mathrm{C}(\mathrm{g})$
If the total pressure of the gases is found to be $200$ torr after $23 \mathrm{sec}$. and $300$ torr upon the complete decomposition of $\mathrm{A}$ after a very long time, then the rate constant of the given reaction is . . . . . .$\times 10^{-2} \mathrm{~s}^{-1}$ (nearest integer)
[Given : $\log _{10}(2)=0.301$ ]
