Chemistry - Chemical Equilibrium Question with Solution | TestHub

The equilibrium constants $K_{P1}$ and $K_{P2}$ for the reactions $X\rightleftharpoons 2Y$ and $Z\rightleftharpoons P+Q$ respectively are in the ratio $1:9$. If the dissociation of X and Z are equal under the given conditions then the ratio of their equilibrium pressures $\left(\frac{P_2}{P_1}\right)$ is
