Consider the reaction given below:
$A + 2 B \longrightarrow 3 C + 2 D$.
If the rate of disappearance of $B$ is $x \times 10^{-2} \ mol \ L^{-1} \ s^{-1}$,the ratio of the rate of reaction and the rate of appearance of $C$ is:

For the reaction $3A \to 2B$,the rate of reaction is expressed as $\frac{+d[B]}{dt} = \dots$

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:

For the reaction,$XA + YB \rightarrow ZC$,if $\frac{- d [ A ]}{ dt } = \frac{- d [ B ]}{ dt } = \frac{d [ C ]}{ dt },$ then the correct statement among the following is:

For the reaction $H_2 + I_2 \rightleftharpoons 2HI$,write the correct relationship between the rates of change of concentration of reactants and products.

Consider the reaction,$2 NO_{2(g)} \rightarrow 2 NO_{(g)} + O_{2(g)}$. In the figure below,identify the curves $X, Y$ and $Z$ associated with the three species in the reaction.
