Enter the role of a catalyst many important chemical reactions require inputs of energy to proceed if a catalyst is present less energy will be required to complete the reaction why are catalysts important to chemical reactions. Heterogeneous catalysts a study guide discussion questions what are chemical absorptions and how do they promote chemical reactions what types of chemisorption lead to the poisoning of a catalyst how transition metals are chosen as catalysts. In chemistry and biology, catalysis is the acceleration (increase in rate) of a chemical reaction by means of a substance, called a catalyst, that is itself not consumed by the overall reaction a catalyst decreases the activation energy of a chemical reaction catalysts participate in reactions but are neither reactants nor products of the. 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 this process is called catalysis a catalyst is not consumed by the reaction and it may participate in multiple reactions at a time the only.
