Kinetics and Rate Equations · Chemical Reactions

Reaction Mechanisms

Proposing step by step sequences of elementary reactions that match experimental rate laws.

Key Questions

  1. 1How does the rate determining step limit the overall speed of a reaction?
  2. 2What evidence do we have for the existence of reaction intermediates?
  3. 3How do catalysts provide alternative pathways with lower activation energy?
