**Gas Phase Decomposition of Nitrogen Dioxide**In this exercise, we will explore the gas phase decomposition of nitrogen dioxide at a temperature of 383 °C. The decomposition reaction is represented by the following chemical equation:\[ \text{NO}_2(\text{g}) \rightarrow \text{NO}(\text{g}) + \frac{1}{2} \text{O}_2(\text{g}) \]This reaction is second-order with respect to \(\text{NO}_2\), and the rate constant (\(k\)) for this reaction is \(0.540 \, \text{M}^{-1} \text{s}^{-1}\).**Problem Statement:** Determine the concentration of \(\text{NO}_2\) after 20.7 seconds, given that the initial concentration of \(\text{NO}_2\) is \(0.446 \, \text{M}\).**Calculation:**For a second-order reaction, the relationship between the concentration of reactant and time is given by:\[ \frac{1}{[\text{NO}_2]} = \frac{1}{[\text{NO}_2]_0} + kt \]Here:- \([\text{NO}_2]\) is the concentration of \(\text{NO}_2\) at time \(t\)- \([\text{NO}_2]_0\) is the initial concentration of \(\text{NO}_2\)- \(k\) is the rate constant- \(t\) is the timeGiven data:- \([\text{NO}_2]_0 = 0.446 \, \text{M}\)- \(k = 0.540 \, \text{M}^{-1} \text{s}^{-1}\)- \(t = 20.7 \, \text{s}\)To find the concentration of \(\text{NO}_2\) after 20.7 seconds, substitute the given values into the second-order rate equation:\[ \frac{1}{[\text{NO}_2]} = \frac{1}{0.446 \, \text{M}} + (0.540 \, \text{M}^{-1} \text{s}^{-1})(20.7 \, \text{s}) \]Calculate the term on the right-hand side:\[ \frac
