1. The following data were obtained for the reaction: 2 NO2 (g) 2 NO (g) + O (g) 3. Time (s) 0 20 40 60 [NO] M 0.8333 0.4167 0.2778 0.2083 In [NO2] 1/[NO2] (a) Calculate the natural logarithm and reciprocal for each value of [NO]. (b) Plot [NO] versus time, In[NO] versus time and 1/[NO] versus time. Which graph yields the best straight line? (c) What is the reaction order with respect to NO? Write the rate law for this reaction. 2. In this experiment, the solution is going from purple to colorless. Should the percent transmittance increase or decrease through the reaction? Explain. The Procedure requires you set the wavelength at 595 nm. Why do you need to measure the absorbance at this wavelength? (Hint: explain in terms of visible spectrum and complementary colors - absorbed radiation versus reflected radiation). 1.
