7 things you may not know about catalysis

WebCatalysts work by providing an alternative reaction pathway by lowering the activation energy needed for this new pathway. With lower activation energy, more collisions will … WebThe effect of a catalyst is that it lowers the activation energy for a reaction. Generally, this happens because the catalyst changes the way the reaction happens (the mechanism). We can visualize this for a simple reaction … may third 1999 tornado
