\(\mathrm{KClO}_{3}+6 \mathrm{FeSO}_{4}+3 \mathrm{H}_{2} \mathrm{SO}_{4} \rightarrow \mathrm{KCl}+3 \mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3}+3 \mathrm{H}_{2} \mathrm{O}\)

The above reaction was studied at \(300 \mathrm{~K}\) by monitoring the concentration of \(\mathrm{FeSO}_{4}\) in which initial concentration was \(10 \mathrm{M}\) and after half an hour became 8.8 M. The rate of production of \(\mathrm{Fe}_{2}\left(\mathrm{SO}_{4}\right)_{3}\) is _________ \(\times 10^{-6} \mathrm{~mol} \mathrm{~L} \mathrm{~s}^{-1}\) (Nearest integer)
