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

For an elementary reaction $2A + B \longrightarrow 3C$,the rate of appearance of $C$ is $1.3 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. The rate of disappearance of $A$ is:

For the reaction,$N_2 + 3H_2 \rightarrow 2NH_3,$ if $\frac{d[NH_3]}{dt} = 2 \times 10^{-4} \ mol \ L^{-1} \ s^{-1},$ the value of $-\frac{d[H_2]}{dt}$ would be .................. $mol \ L^{-1} \ s^{-1}$.

For the decomposition reaction $N_2O_{4(g)} \rightarrow 2NO_{2(g)}$,the initial pressure of $N_2O_4$ decreases from $0.46 \ atm$ to $0.28 \ atm$ in $30 \ minutes$. What is the rate of formation of $NO_2$?

For the reaction,$3A + 2B \to C + D$,the differential rate law can be written as:

For the reaction,$NO_{2(g)} + CO_{(g)} \rightarrow NO_{(g)} + CO_{2(g)}$,the rate of formation of $NO_{(g)}$ is $Y$ (in $mol \ dm^{-3} \ s^{-1}$). Find the rate of disappearance of $CO_{(g)}$ (in $mol \ dm^{-3} \ s^{-1}$)?
