Derivation The Arrhenius equation can be written as: k = Ae Consider a reaction with some activation energy that we will call Ea1-Suppose a catalyst is added to the reaction that binds to the transition state and lowers the activation energy to a new E, that we can call E 2. We can define the difference in catalyzed and uncatalyzed activation energies as AEG-Ea2-E1- The rate enhancement due to the presence of a catalyst can be defined as where k₁ is the rate constant of the reaction without the catalyst, and k2 is the rate constant of t process with the catalyst, both at some constant temperature T. Derive an expression for the rate enhancement in terms of T and AE, and select an equivalent equation from the list below. k²= In (46) O O k₂ AE =eR = In (e 12 = 46 ) = In (AF)
