Mechanisms of Reactions
A chemical equation accurately portrays the nature of the starting and final materials in a chemical reaction, but the arrow conveniently covers our ignorance of what happens in between. How many steps are there in the overall process? What are the spatial and energetic requirements in each step? What is the rate of each step? Although rate measurements usually describe only the overall reaction, the measurement of rates under different conditions often contribute to an understanding of the mechanism.
