${\mathrm{NO}}_2$required for a reaction is produced by decomposition of${\mathrm{N}}_2{\mathrm{O}}_5$in${\mathrm{CCl}}_4$as by equation$2{\mathrm{N}}_2{\mathrm{O}}_{5( \mathrm{g})}\to 4{\mathrm{NO}}_{2( \mathrm{g})}+{\mathrm{O}}_{2( \mathrm{g})}$
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}$$\min -1$, value of$\mathrm{x}$is ________.
