Chemistry Question from JEE Main 2023 · 1 February, Shift 1

(i) $X\text{(g)}$ $\rightleftharpoons$ $Y\text{(g)}$ + $Z\text{(g)}$, $K_{p1} = 3$

(ii) $A\text{(g)}$ $\rightleftharpoons$ $2B\text{(g)}$, $K_{p2} = 1$

If the degree of dissociation and initial concentration of both the reactants $X\text{(g)}$ and $A\text{(g)}$ are equal, then the ratio of the total pressure at equilibrium $\left( \frac{P_1}{P_2} \right)$ is equal to $x : 1$. The value of $x$ is _____. (Nearest integer)
