The purpose of this experiment is to focus on four different factors and how they may affect the rate of a chemical reaction. The four factors are: concentration of reactants, temperature, surface area, and the presence of a catalyst. Introduction The rate of a chemical reaction can be defined as the amount of substance produced over a certain time. Rates of reactions can be determined with the rate law formula: rate=k[A]^m[B]^n. Variables A and B are the molarities of the reactants, while m and n are usually zero, one, two, or three. “K” is a constant that is proportional to the temperature of the reaction. Temperature can very noticeably make a reaction slower or faster. Reactions also have to have a certain minimum activation energy level in order to be completed. This activation energy comes from kinetic energy produced by particle collisions.

    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.
