Protoreaktio

Protoreaktio is a term used in chemistry to describe a chemical reaction that occurs very rapidly, often approaching the timescale of molecular collisions. These reactions are characterized by extremely short-lived intermediate states, if any are formed at all. In a protoreaction, the reactants transform directly into products without a well-defined energy barrier that needs to be overcome. This contrasts with typical chemical reactions that proceed through a distinct transition state with a higher energy than both reactants and products.

The concept of protoreaction is particularly relevant in areas like gas-phase kinetics and theoretical chemistry. Studying protoreactions can provide insights into fundamental chemical processes and the limits of chemical reaction rates. The very fast nature of these transformations makes them challenging to study experimentally using conventional techniques, often requiring specialized spectroscopic methods or computational simulations to probe their mechanisms. The absence of a significant activation energy means that these reactions are less sensitive to temperature changes compared to slower reactions.
