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.
The process by which one or more substances change to produce one or more different substances.
