The equilibrium constants for the reactions $\mathrm{X}=2 \mathrm{Y}$ and $\mathrm{Z}=\mathrm{P}+\mathrm{Q}$ are $\mathrm{K}_{1}$ and $\mathrm{K}_{2}$, respectively. If the initial concentrations and the degree of dissociation of $Z$ and $Z$ are the same, the ratio $\mathrm{K}_{1} / \mathrm{K}_{2}$ is.
