$1\,L$ Solution $( X )+ AgNO _3$ solution (excess) $\rightarrow Y$
$1\,L$ Solution $( X )+ BaCl _2$ solution (excess) $\rightarrow Z$
The number of moles of $Y$ and $Z$ respectively are
Step$-1$ : ${\text{A + E }} \rightleftharpoons AE$ (fast)
Step$-2$ :${\text{AE + A }} \to {A_2} + E$ (slow)
Step$-3$ :${{\text{A}}_2}{\text{ + B }} \to {\text{D}}$ (fast)
