What is the difference between intermediates and transition states?

An intermediate differs from a transition state in that the intermediate has a discrete lifetime (be it a few nanoseconds or many days), whereas a transition state lasts for just one bond vibration cycle. An intermediate may be an unstable molecule (a reactive intermediate) or a highly stable molecule.

What is an intermediate in a chemical reaction?

chemical intermediate, any chemical substance produced during the conversion of some reactant to a product. All the substances generated by one step and used for the succeeding step are considered intermediates.

What is a transition state in a chemical reaction?

The transition state is a high-energy state, and some amount of energy – the activation energy – must be added in order for the molecule reach it. Because the transition state is unstable, reactant molecules don’t stay there long, but quickly proceed to the next step of the chemical reaction.

What is the difference between the reactants and the transition state?

According to transition state theory, between the state in which molecules exist as reactants and the state in which they exist as products, there is an intermediate state known as the transition state. The species that forms during the transition state is a higher-energy species known as the activated complex.

How do reaction intermediates differ from activated complexes?

Reaction intermediates differ from activated complexes in that: they are intermediate structures which have characteristics of both reactants and products. they are molecules with normal bonds rather than partial bonds and can occasionally be isolated.

What are intermediates and transition species?

Transition state is just the state before formation of new molecules (involves breaking of bonds of reactants and formation of new ones). An intermediate is a reactive species formed during the reaction. Its energy is less than that of corresponding transition state.
