$(i)$ ${C_4}{H_5}N{H_2}$ $(ii)$ $C{H_3}N{H_2}$
$(iii)$ ${(C{H_3})_2}NH$ $ (iv)$ ${(C{H_3})_3}N$
$\gamma_{1} A +\gamma_{2} B \rightarrow \gamma_{3} C +\gamma_{4} D$
Concentration of $C$ changes from $10\, mmol$ appearance of $D$ is $1.5$ times the rate of disappearance of $B$ which is twice the rate of disappearance $A$. The rate of appearance of $D$ has been experimentally determined to be $9 \,m\,mol$ $dm ^{-3} s ^{-1}$. Therefore the rate of reaction is $......\,m\,mol\, dm ^{-3} \,s ^{-1}$. (Nearest Integer)
