\(\mathrm{NO}_2\) required for a reaction is produced by decomposition of \(\mathrm{N}_2 \mathrm{O}_5\) in \(\mathrm{CCl}_4\) as by equation

\(2 \mathrm{~N}_2 \mathrm{O}_{5(\mathrm{~g})} \rightarrow 4 \mathrm{NO}_{2(\mathrm{~g})}+\mathrm{O}_{2(\mathrm{~g})}\)

The initial concentration of \(\mathrm{N}_2 \mathrm{O}_5\) is \(3 \mathrm{~mol} \mathrm{~L}^{-1}\) and it is \(2.75 \mathrm{~mol} \mathrm{~L}^{-1}\) after 30 minutes.

The rate of formation of \(\mathrm{NO}_2\) is \(\mathrm{x} \times 10^{-3} \mathrm{~mol} \mathrm{~L}^{-1} \mathrm{~min}^{-1}\), value of \(\mathrm{x}\) is _________. (nearest integer)
