For the decomposition of dinitrogen pentoxide in carbon tetrachloride solution at $30C$

$2N_2{O}_5$longrightarrow$4N{O}_2+O_2$

the average rate of disappearance of $N_2{O}_5$ over the time period from $t=0$min to $t=106$min is found to be $2\mathrm{.}05{10}^{-3}Mmi{n}^{-1}.$

The average rate of formation of $O_2$ over the same time period is

M
