The decomposition of NOBr is studied manometrically (with a manometer) because the number of moles of gas changes; it cannot be studied colorimetrically (with a spectrometer measuring the change in absorbance) because both NOBr and Brz are reddish brown: 2NOBr(g) → 2 N0(g) + Brz(g) Use the data provided to answer the following: a. Find the average rate over the entire experiment. b. What is the average rate from 2.00 to 4.00 seconds? c. Use graphical methods to estimate the initial rate. By “graphical methods" I mean draw a graph and estimate by drawing a tangent line and finding the slope. d. At what time does the instantaneous rate equal to the average rate over the entire experiment? Hint: How does the slope representing this instantaneous rate compare to the line corresponding to a?
