Atmospheric Chemistry Lecture 1: Chemical Principles and ...
www2.acom.ucar.eduThe speed of a chemical reaction is called the reaction rate. The science that deals with reaction rates is called chemical kinetics. A basic understanding of chemical kinetics is crucial to atmospheric chemistry. In chemical kinetics-speak, unimolecular reactions are part of a class of reactions called first-order reactions:
Oscillating Chemical Reactions - Campus Tour
inside.mines.eduacquaintance with chemistry, these reactions are a mystery and a challenge. To everyone, they are memorable demonstrations of the wonder of chemistry. Perhaps what makes oscillating reactions so fascinating to chemists is that they seem to contradict common sense. Experience tells us that, under a given set of conditions, chemical reactions go in

Our bodies also contain thousands of catalysts in the form of enzymes, which chisel out the molecules necessary for life. Catalysts are thus fundamental tools for chemists, but
