Nitrogen dioxide gas dissociates to give nitric oxide and oxygen. For this reaction, when a graph is ploted between concentration of `NO_(2)` and time, the slope of tangent drawn at time t=10 s is found to be `6.8xx 10^(-4)` mol `L^(-1) s^(-1)` .predict the slope of the graph at t=10s when the concentration of NO and `O_(2)` are plotted against time. Justify your answer.

Explanation

To solve the problem, we need to analyze the dissociation reaction of nitrogen dioxide (NO2) into nitric oxide (NO) and oxygen (O2):

**Step 1: Write the balanced chemical equation.**
The dissociation of nitrogen dioxide can be represented as:
\[ 2 \text{NO}_2(g) \rightarrow 2 \text{NO}(g) + \text{O}_2(g) \]

**Step 2: Understand the relationship between the rates of change of concentrations.**
From the balanced equation, we can express the rates of change of the concentrations:
