The equilibrium constants $K_{P1}$ and $K_{P2}$ 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:

Oxidizing power of chlorine in aqueous solution can be determined by the parameters:$\frac{1}{2}{\text{Cl}}_2(g)\stackrel{\frac{1}{2}{\Delta }_{\text{diss}}H}{\to }\text{Cl}(g)\stackrel{{\Delta }_{\text{eg}}H}{\to }{\text{Cl}}^{-}(g)\stackrel{{\Delta }_{\text{hyd}}H}{\to }{\text{Cl}}^{-}(aq)$ Using the data:${\Delta }_{\text{diss}}{H}_{{\text{Cl}}_2}=240\text{kJ/mol}$${\Delta }_{\text{eg}}{H}_{\text{Cl}}=-349\text{kJ/mol}$${\Delta }_{\text{hyd}}{H}_{\text{Cl}}=-381\text{kJ/mol}$ The energy involved in the conversion of $\frac{1}{2}{\text{Cl}}_2(g)$ to ${\text{Cl}}^{-}(aq)$ will be:
