A batch reaction system is used to carry out the reaction

$2N{O}_2^{-}+O_{2}2N{O}_3^{-}$

If the rate of reaction of $N{O}_2^{-}-N$ can be described by a saturation$-$

type expression

where

$k_{N{O}_2^{-}}=7\frac{g}{m^3}*d$

$K_{N{O}_2}=0\mathrm{.}1\frac{g}{m^3}$

plot $C_{N{O}_2^{-}}$and $C_{N{O}_3^{-}}$in grams per cubic meter as a function of

time if $C_{N{O}_{20}}^{-}=3\mathrm{.}0\frac{g}{m^3}$ and $C_{N{O}_3}^{-}=0.$ All concentrations are in

terms of $N.$

In this equation $r_{NO2-}=d\frac{C_{NO2}}{d}t$ To solve you can rearrange to get $dt$ on one side and the

concentration terms on the other and then integrate. You will get a solution where you input a

concentration and calculate the time it takes to get to that concentration.
