Chemistry - Chemical Equilibrium Question with Solution | TestHub

The equilibrium constants $K_{P_1}$ and $K_{P_2}$ for the reactions $X\rightleftharpoons 2Y$ and $Z\rightleftharpoons P+Q$, respectively are in the ratio of $1:9$. If the degree of dissociation of $X$ and $Z$ be equal then the ratio of total pressure at these equilibria is
