How catalysts affect activation energy
WebThe effect of a catalyst on the activation energy is shown on a chart called a reaction profile. This shows how the energy of the reactants and products change during a reaction. WebCatalysts are defined as substances that participate in a chemical reaction but are not changed or consumed. Instead they provide a new mechanism for a reaction to occur which has a lower activation energy than that of the reaction without the catalyst.

WebEnzymes and activation energy A substance that speeds up a chemical reaction—without being a reactant—is called a catalyst. The catalysts for biochemical reactions that happen in living organisms are called enzymes. Enzymes are usually proteins, though some ribonucleic acid (RNA) molecules act as enzymes too. Web... effect of the catalyst is purely kinetic; catalysts work by providing an alternative mechanism that involves a different transition state and lower activation energy ( Figure 1 ). The...
Web(3) Flexible adaption of catalyst structure and electron distribution along the reaction path are essential for energy minimization and thus lowering the activation energy, while mobility and dynamics of the adsorbed substrate reduce the activation entropy and keep the Arrhenius pre-exponential factor high.
