For the reaction $CH_3COOCH_3 + H_2O \xrightarrow{H^{+}} CH_3COOH + CH_3OH$,the progress of the reaction is followed by:

$KClO_3 + 6FeSO_4 + 3H_2SO_4 \rightarrow KCl + 3Fe_2(SO_4)_3 + 3H_2O$. The above reaction was studied at $300 \ K$ by monitoring the concentration of $FeSO_4$,where the initial concentration was $10 \ M$ and after half an hour it became $8.8 \ M$. The rate of production of $Fe_2(SO_4)_3$ is $........ \times 10^{-6} \ mol \ L^{-1} \ s^{-1}$.

For the reaction ${N_2}_{(g)} + 3{H_2}_{(g)} \to 2N{H_3}_{(g)}$,what is the relationship between $\frac{d[N{H_3}]}{dt}$ and $-\frac{d[{H_2}]}{dt}$?

For the reaction $N_2 + 3H_2 \rightarrow 2NH_3$ in the Haber process,the rate of formation of $NH_3$ is $2.5 \times 10^{-4} \ mol \ L^{-1} \ s^{-1}$. What is the rate of disappearance of $N_2$?

Nitric oxide reacts with $H_2$ according to the reaction,$2 NO_{(g)} + 2 H_{2(g)} \rightarrow N_{2(g)} + 2 H_2O_{(g)}$. Identify the correct relationship among the following.

Find the average rate of formation of $NO_{2_{(g)}}$ in the following reaction:
