Definition
The transition state in a chemical reaction is a particular configuration along the reaction path. It is defined as the state corresponding to the highest potential energy along this path.
This refers to how quickly or slowly reactants turn into products in a chemical reaction. Imagine if you could run up that hill super fast - that would be a high reaction rate!
Potential Energy Diagrams: These are diagrams that show changes in potential energy as reactions progress. They're like maps showing you how steep your climb will be and where your transition state (the peak) lies.
