How catalysts affect activation energy
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. (4) There exists an optimum binding energy of … WebEffect of catalysts The rate of a reaction can be increased by adding a suitable catalyst. A catalyst is a substance which increases the rate of a chemical reaction but it is not used up (remains...
