Reaction Mechanisms 1 An AP Chemistry In-Class Activity 1) What is a reaction mechanism? 2) What is an elementary step? Use an example. 3) In finding the sum of proposed elementary steps, what did you do last semester that had a similar process? How does this process work? 4) What is the rate-limiting step? Give an example. Why is it important? 5) What is meant by an unstable intermediate? What is it the intermediate between? 6) What does molecularity mean? 7) How are the rate laws (1st order, 2nd order) related to molecularity?

    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.
