Transition State Theory
Mediumchemistry
Transition state is best described as:
Select the correct option:
Solution
Incorrect! Answer:
Species at energy maximum along reaction path
- Reaction Path: The path of least energy connecting reactants to products.
- Mechanism: As reactants approach, bonds distort. This leads to a peak in potential energy.
- The Transition State (TS): The specific configuration of atoms at the very peak of the energy barrier.
- Properties: It is highly unstable, cannot be isolated, and is sometimes called the Activated Complex.
- Direction: It can decompose back to reactants or proceed forward to form products.
- Comparison: An intermediate is a species located at a local minimum on the energy path and can sometimes be isolated.
