Catalysts: Paul Andersen explains how catalysts can speed up a reaction without being consumed in the reaction. Catalysts can lower the activation energy of reaction be stabilizing the transition state. They can also create new reaction pathways with new reaction intermediates that lower the overall activation energy.
Chemistry Lab: Types Of Chemical Reactions. The purpose of this lab is: 1) To observe some chemical reactions and identify reactants and products of those reactions. 2) To classify the reactions and write balanced equations. $
The process by which one or more substances change to produce one or more different substances.
