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 $5Br^-{_{\text{(aq)}}} + 6H^+{_{\text{(aq)}}} + BrO_3^-{_{\text{(aq)}}} \rightarrow 3Br_{2\text{(aq)}} + 3H_2O_{\text{(l)}}$. If $-\frac{\Delta[BrO_3^{-}]}{\Delta t} = 0.01 \ mol \ L^{-1} \ min^{-1}$,calculate $\frac{\Delta[Br_2]}{\Delta t}$ in $mol \ L^{-1} \ min^{-1}$.

In the following reaction $3A \to B + 2C$,the initial concentration of $A$ is $8\,mol\,L^{-1}$. After $10\,min$,it becomes $5\,mol\,L^{-1}$. Find the rate of reaction in $mol\,L^{-1}\,min^{-1}$.

In the reaction of formation of sulphur trioxide by contact process $2SO_2 + O_2 \rightleftharpoons 2SO_3$,the rate of reaction was measured as $\frac{d[O_2]}{dt} = -2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. The rate of reaction in terms of $[SO_2]$ in $mol \ L^{-1} \ s^{-1}$ will be:

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 $mol \ dm^{-3} \ s^{-1}$)?

In the reaction $2N_2O_5(g) \rightarrow 4 NO_2(g) + O_2(g)$, $N_2O_5$ disappears at a rate of $0.06 \text{ mol dm}^{-3} \text{s}^{-1}$. Calculate the rate of formation of $O_2(g)$.
