3. Write down a complete set of rate equations for the mechanism 4. What is the overall reaction? 5. The empirical rate law for this reaction is . What does this tell us about the elementary reactions? How is k related to the rate constants of the two steps? 4. Proflavin is a large aromatic ion used to stain DNA: Like many other planar aromatic species, proflavin dimerizes in water: where P is a proflavin ion and D is the dimer. The rate constants have been measured by a technique which we shall discuss later. They are Calculate the equilibrium constant for the dimerization reaction. 5. Suppose that the reaction has an empirical rate law v = ka when studied in water. Is it possible that the rate-determining step of the reaction involves water? How could you test this experimentally? 6. has a half-life of 28.1y. This radioisotope is particularly hazardous because it becomes incorporated in bones so that it remains in the body and is never excreted. If a person accidentally ingests of , how much will remain after 40y? 7. The reaction of ethyl acetate with hydroxide to form acetate ions and ethanol has a rate law

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
