Question

Decomposition of NO2(g) at 300 °C yields the data in the table. Plots of In[NO2] and 1/[NO2] are shown below. The rate constant for this reaction at 300 °C is . (Hint: The units are based on the reaction order.) Report your answer with two significant figures. Do NOT include units in your answer. 2 NO2(g) → 2NO(g) + O2(g) Time (s) [NO2] (M) 0.0 0.0100 50.0 0.00787 100.0 0.00649 200.0 0.00481 300.0 0.00380
