$$\mathrm{KClO}_3+6 \mathrm{FeSO}_4+3 \mathrm{H}_2 \mathrm{SO}_4 \rightarrow \mathrm{KCl}+3 \mathrm{Fe}_2\left(\mathrm{SO}_4\right)_3+3 \mathrm{H}_2 \mathrm{O} $$The above reaction was studied at $\displaystyle 300$ K by monitoring the concentration of $\displaystyle \mathrm{FeSO}_4$ in which initial concentration was $\displaystyle 10$ M and after half an hour became $\displaystyle 8.8$ M . The rate of production of $\displaystyle \mathrm{Fe}_2\left(\mathrm{SO}_4\right)_3$ is $\displaystyle \_\_\_\_$ $\displaystyle \times 10^{-6} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~s}^{-1}$.
