$KClO_3 + 6FeSO_4 + 3H_2SO_4 \rightarrow KCl + 3Fe_2(SO_4)_3 + 3H_2O$. 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 $........ \times 10^{-6} \ mol \ L^{-1} \ s^{-1}$.

The rate of a gaseous reaction is given by $r = K[x][y]$. If the volume of the reaction vessel is suddenly reduced to $1/4$ of its initial volume,the rate of the reaction will ............

At a definite temperature and pressure,the rate of a reaction depends on which of the following factors?

For the elementary reaction $2 SO_{2(g)} + O_{2(g)} \rightarrow 2 SO_{3(g)}$,identify the correct relation among the following.

For the reaction $2 NH_{3(g)} \rightarrow N_{2(g)} + 3 H_{2(g)}$,the rate of disappearance of $NH_3$ is $1.2 \times 10^{-3} \ mol \ L^{-1} \ s^{-1}$. What is the rate of formation of $N_2$ and $H_2$?

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)
