Explaining how and why factors affect reaction rates. The Maxwell-Boltzmann apparatus. Maxwell and Boltzmann performed an experiment to determine the kinetic energy distribution of atoms. Because all atoms of an element have roughly the same mass, the kinetic energy of identical atoms is determined by velocity (KE= . Chem.

How? By providing a new pathway for the reaction, one with a lower activation energy. Catalyzed Reaction. Note: a greater fraction of the collisions are effective therefore the reaction rate increases.

That is, the transition state must be boundbetter than the ground CHAPTER 2: Surface Chemistry INTRODUCTION Surface Chemistry is closely related to interface and colloidal science. Surface chemistry is important in many criticalchemical processes, such as enzymatic OC VI (HS 2015) www.bode.ethz.ch Page 1 This work is licensed under a Creative Commons Attribution - NonCommercial - ShareAlike 4.0 International License .

Thermodynamics. is concerned with only the initial and final states of a process, being independent of the path(s) between the two states.. Kinetics. is concerned with the rate at which the process occurs and thus is concerned with the path(s) between the two states..
