(i) X ( g ) ⇌ Y ( g )+ Z ( g ) K_p 1 =3 (ii) A ( g ) ⇌ 2 B ( g ) K_p 2 =1 If the degree of dissociation and initial concentration of both the…
(i)
$$\mathrm{X}(\mathrm{~g}) \rightleftharpoons \mathrm{Y}(\mathrm{~g})+\mathrm{Z}(\mathrm{~g}) \quad \mathrm{K}_{\mathrm{p} $\displaystyle 1$}=$\displaystyle 3$
$$(ii)
$$
\mathrm{A}(\mathrm{~g}) \rightleftharpoons $\displaystyle 2$ \mathrm{~B}(\mathrm{~g}) \quad \mathrm{K}_{\mathrm{p} $\displaystyle 2$}=$\displaystyle 1$
$$If the degree of dissociation and initial concentration of both the reactants $\displaystyle \mathrm{X}(\mathrm{g})$ and $\displaystyle \mathrm{A}(\mathrm{g})$ are equal, then the ratio of the total pressure at equilibrium $\displaystyle \left(\frac{p_1}{p_2}\right)$ is equal to $\displaystyle \mathrm{x}: 1$. The value of x is $\displaystyle \_\_\_\_$ (Nearest integer)
