Consider this reaction: 2HI (g) → H, (g) +I, (g) At a certain temperature it obeys this rate law. rate = (0.118 M-s)[H] ? Suppose a vessel contains HI at a concentration of 1.48 M. Calculate the concentration of HI in the vessel 42.0 seconds later. You may assume no other reaction is important. Round your answer to 2 significant digits. x10 II

6. Identify the reagents that would allow accomplishing each of the following transformations. More than one reagent and one step may be required. Pay close attention to stereochemistry. As a good practice, determine if the reaction goes through SN1 or SN2 mechanism.
