Chemical Kinetics - Catalysis
3 important questions on Chemical Kinetics - Catalysis
What does a catalyst do?
It lowers the activation energy of a reaction (in different ways) Irregardless of the mechanism, a catalyst only affats the rate of reaction, and not the equilibrium ratio of products to ractants.
What is Pauling's principle?
The rate enhancement by te catalyst is proportional to the binding affinity of the catalust for the transition state.
2 important implications:
It states that you kshould design a catalyst that binds tightly to the transition state (and not the reactants)a catalyst reduces the transition-state free energy for the forward reaction is also a catalyst for the backward reaction.

What is the thermodinamic driving force for the oscillations in the concentrations of intermediate and catalyst species in the BZ reaction?
The monotomic decrease in free energy as the overall reaction occurs.
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
Remember faster, study better. Scientifically proven.
