For a chemical reaction $4 A + 3 B \rightarrow 6 C + 9 D$,the rate of formation of $C$ is $6 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$ and the rate of disappearance of $A$ is $4 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$. The rate of reaction and the amount of $B$ consumed in an interval of $10 \ s$,respectively,will be:

  • A
    $1 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$ and $30 \times 10^{-2} \ mol \ L^{-1}$
  • B
    $10 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$ and $10 \times 10^{-2} \ mol \ L^{-1}$
  • C
    $1 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$ and $10 \times 10^{-2} \ mol \ L^{-1}$
  • D
    $10 \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$ and $30 \times 10^{-2} \ mol \ L^{-1}$

For a given chemical reaction $\gamma_{1} A + \gamma_{2} B \rightarrow \gamma_{3} C + \gamma_{4} D$,the rate of appearance of $D$ is $1.5$ times the rate of disappearance of $B$,which is twice the rate of disappearance of $A$. The rate of appearance of $D$ has been experimentally determined to be $9 \, mmol \, dm^{-3} s^{-1}$. Therefore,the rate of reaction is $...... \, mmol \, dm^{-3} s^{-1}$. (Nearest Integer)
