Catalysts work by providing…. “AN ALTERNATIVE REACTION PATHWAY WHICH HAS A LOWER ACTIVATION ENERGY”. for the uncatalyzedone.To achieve catalysis, the catalyst must stabilize the transitionstate more than it stabilizes the ground state. That is, the transition state must be boundbetter than the ground CHAPTER 2: Surface Chemistry INTRODUCTION Surface Chemistry is closely related to interface and colloidal science. Surface chemistry is important in many criticalchemical processes, such as enzymatic CATALYSIS APPLICATIONS Catalysis Applications Catalysis is the process of increasing the rate of a chemical reaction by the addition of a substance known as a catalyst.
