Solution
Correct 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.
This medium difficulty chemistry question is from the chapter chemical kinetics, covering the topic of transition state theory. It appeared in the 2025 exam.
