5.3 Concentration Changes Over Time
![Plot of \(\dfrac{1}{[\text{NO}_2]}\) versus time for the decomposition of \(\text{NO}_2\text{(g)}\) at \(573\text{ K}\).](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1787300222-b2vhdR.jpg)
\[ 2\text{NO}_2\text{(g)} \rightarrow 2\text{NO(g)} + \text{O}_2\text{(g)} \]
The student measures the concentration of \(\text{NO}_2\text{(g)}\) over time and plots \(\dfrac{1}{[\text{NO}_2]}\) as a function of time, as shown in the graph below.
Based on the graph, what is the value of the rate constant, \(k\), for the reaction?
