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= . Mechanisms. C483 Spring 2013. Questions. 1. .

That is, the transition state must be boundbetter than the ground Supramolecular reactivity and catalysis thus involve two main steps : (i) Binding : which selects the substrate, and (ii) Transformation : of the bound species into products within the supermolec CATALYSIS APPLICATIONS Catalysis Applications Catalysis is the process of increasing the rate of a chemical reaction by the addition of a substance known as a catalyst.
