The actual sequence of the individual elementary reactions is known as reaction mechanism.

Research relevance Enhance the understanding of elementary reaction steps in catalytic cycles.

Consider a particular collision (an elementary reaction) between molecules A and B.

The whole reaction scheme was satisfactorily modeled by a network of 14 elementary reactions.

Rate constant can be calculated for elementary reactions by molecular dynamics simulations.

It is concluded that the concept cannot be generally applied even to elementary reactions in ideal homogeneous systems.

Modelling of steric bulk and solvation effects in elementary reaction steps.

Transition states can be unstable intermediate molecular states even in the elementary reactions.

However, we can consider the molecularity of the individual elementary reactions that make up this mechanism:

Elementary reaction steps with order 3 (called ternary reactions) are rare and unlikely to occur.

The conditions under which this state can be used as a source of H atoms for the study of elementary reactions have been investigated.

That would be fine for determining elementary reactions, but I can't carry around a machine shop; it wouldn't be practical.

It may also be useful to keep the elementary reactions and chemical dissociations for calculating emissions.

Issues with molecular dissociation and elementary reactions with variable composition.

An elementary reaction involves a few molecules, usually one or two, because of the low probability for several molecules to meet at a certain time.

The most important elementary reactions are unimolecular and bimolecular reactions.

There are two objections to associating this activation energy with the threshold barrier for an elementary reaction.

A second is that most chemical reactions occur as a sequence of elementary reactions, each with its own transition state.

For elementary reactions, which consist of a single step, the order equals the molecularity as predicted by collision theory.

Note that this definition includes the elementary reactions:

Another is that paper is a "complex system" and the Arrhenius equation only applicable to elementary reactions.

The C represents a chemical reaction which can be any elementary reaction step and is often called a "following" reaction.

Equilibrium constants can be expressed in terms of the rate constants for elementary reactions.

For example, it may be that the intermediates have been detected, but it is not known by which mechanisms the actual elementary reactions occur.

Accordingly, a chemical reaction may be an elementary reaction or a stepwise reaction.
