WebCollision Theory- According to the collision theory, the molecules of reactants are assumed to be hard spheres and the reactions are assumed to occur only when these spheres (molecules) collide with each other. The number of collisions that take place per second per unit volume of the reaction mixture is known as collision frequency. To learn more about … Webcatalyst, in chemistry, any substance that increases the rate of a reaction without itself being consumed. Enzymes are naturally occurring catalysts responsible for many essential biochemical reactions. Most solid catalysts are metals or the oxides, sulfides, and halides of metallic elements and of the semimetallic elements boron, aluminum, and silicon. … WebDiagram shows that a catalyst increases the rate of a reaction by providing an alternative pathway which has a lower activation energy. Catalysts provide the reactants another pathway which has a lower activation energy. By lowering Ea, a greater proportion of molecules in the reaction mixture have sufficient energy for an effective collision. hawaiian dancing maui
