This process is called catalysis. It builds the equivalent of a paved highway to bypass a bumpy dirt road. A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. A reversible chemical reaction can occur in both directions, in that reactants can turn into products and products can turn into reactants. A catalyst is a chemical substance that affects the rate of a chemical reaction by altering the activation energy required for the reaction to proceed. Catalyst: A catalyst is a substance that increases the rate of a chemical reaction, without undergoing any permanent chemical change. Physical chemistry is the branch of chemistry devoted to the study of the behavior of matter at an atomic or molecular level. Enzyme: An enzyme is a biological molecule produced by living organisms, which catalyzes a specific biochemical reaction at body temperatures. Finely divided (powdered) catalyst is more effective than lump catalyst. Catalyst is a common word that you might come across while studying chemistry especially while learning about chemical reactions. Click Chemistry Azide-Alkyne Cycloaddition "Click Chemistry" is a term that was introduced by K. B.
