WebCatalysts and activation energy To increase the rate of a reaction you need to increase the number of successful collisions. One possible way of doing this is to provide an … WebThe energy required to reach the transition state (the activation energy) constitutes a barrier to the progress of the reaction, limiting the rate of the reaction. Enzymes (and other catalysts) act by reducing the activation energy, thereby increasing the rate of reaction.

WebA catalyst speeds up chemical reactions by breaking and forming bonds. To convert the substrate into the product an initial energy is needed to contort the bonds so they may break. This energy is called the activation energy. Activation energy is the amount of energy needed to begin the bond breaking process in a reaction. WebA catalyst can lower the activation energy for a reaction by: orienting the reacting particles in such a way that successful collisions are more likely reacting with the reactants to form an intermediate that requires lower energy to form the product Some metals e.g. platinum, copper and iron can act as catalysts in certain reactions. daily express transport
