Question:

Consider the following reversible chemical reactions :

$\mathrm{A}_{2}(\mathrm{~g})+\mathrm{Br}_{2}(\mathrm{~g}) \stackrel{\mathrm{k}_{1}}{\rightleftharpoons} 2 \mathrm{AB}(\mathrm{g}) \ldots . .(1)$

$6 \mathrm{AB}(\mathrm{g}) \stackrel{\mathrm{K}_{2}}{\rightleftharpoons} 3 \mathrm{~A}_{2}(\mathrm{~g})+3 \mathrm{~B}_{2}(\mathrm{~g}) \ldots . .(2)$

The relation between $K_{1}$ and $K_{2}$ is :

  1. $\mathrm{K}_{2}=\mathrm{K}_{1}{ }^{3}$

  2. $\mathrm{K}_{2}=\mathrm{K}_{1}^{-3}$

  3. $\mathrm{K}_{1} \mathrm{~K}_{2}=3$

  4. $\mathrm{K}_{1} \mathrm{~K}_{2}=\frac{1}{3}$
