1. indicate the activation energy for the overall reaction on the graph. (You may want to
use a line for the sake of clarity.)
2. Write the elementary reactions that make up the reaction mechanism. 
3. What would you propose as the rate law for this reaction? 
4. Of course, this proposed law is hypothetical. Using the following data collected
experimentally (probably using a UV/vis spectrometer J), determine the rate law for
this reaction. Include reaction order and the value and units for k. Please show your
work, including any graphs you make. (Note: no credit will be given to correct final
answers without supporting work.) Does your experimental rate law match the one you
proposed above?
