$X \rightleftharpoons Y + Z - - - - - - \left( 1 \right)$
$A \rightleftharpoons 2B - - - - - - \left( 2 \right)$
are in ratio of $9 :1$. If degree of dissociation of $X$ and $A$ be equal, then total pressure at equilibrium $(1)$ and $(2)$ are in the ratio
(en-ethylenediamine; $H _{2} N - CH _{2}- CH _{2}- NH _{2}$ )
$A + H_2O + CO_2 \to B$
$B + NaCl \to C + NH_4Cl$
$C\xrightarrow{\Delta }D + {H_2}O + C{O_2}$
