The rate of the reaction $ A\xrightarrow{{}} $ products, at the initial concentration of $ 3.24\times {{10}^{-2}}M $ is nine times its rate at another initial concentration of $ 1.2\times {{10}^{-3}}M $ . The order of the reaction is

The order of reaction is decided by

The decomposition of ${N_2O_5}$ in ${CCl_4}$ at 318 K is studied by monitoring the concentration of ${N2O5}$ in the solution. Initially the concentration of ${N2O5}$ is 2.4 mol $L^{-1}$ and after 200 minutes, it is reduced to 2.00 mol $L^{-1}$. What is the rate of production of $NO_2$ during this period in $mol\, L^{-1} min^{-1}$ ?
