Atom
An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element.

Chemical reaction
A chemical reaction is a process that leads to the transformation of one set of chemical substances to another.

Chemical species
A chemical species is a chemical substance or ensemble composed of chemically identical molecular entities that can explore the same set of molecular energy levels on a characteristic or delineated time scale.

Collision theory
Collision theory is a theory proposed independently by Max Trautz in 1916 and William Lewis in 1918, that qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions.

Cycloaddition
A cycloaddition is a pericyclic chemical reaction, in which "two or more unsaturated molecules (or parts of the same molecule) combine with the formation of a cyclic adduct in which there is a net reduction of the bond multiplicity." The resulting reaction is a cyclization reaction.

Dissociation (chemistry)
Dissociation in chemistry and biochemistry is a general process in which molecules (or ionic compounds such as salts, or complexes) separate or split into smaller particles such as atoms, ions or radicals, usually in a reversible manner.

Ion
An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).
New!!: Elementary reaction and Ion · See more »
Isomerization
In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement e.g. A-B-C → B-A-C (these related molecules are known as isomers). In some molecules and under some conditions, isomerization occurs spontaneously.

Law of mass action
In chemistry, the law of mass action is the proposition that the rate of a chemical reaction is directly proportional to the product of the activities or concentrations of the reactants.

Michaelis–Menten kinetics
Michaelis–Menten saturation curve for an enzyme reaction showing the relation between the substrate concentration and reaction rate. In biochemistry, Michaelis–Menten kinetics is one of the best-known models of enzyme kinetics.

Molecularity
Molecularity in chemistry is the number of molecules that come together to react in an elementary (single-step) reactionAtkins, P.; de Paula, J. Physical Chemistry.

Molecule
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

Radical (chemistry)
In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has an unpaired valence electron.
New!!: Elementary reaction and Radical (chemistry) · See more »
Rate equation
The rate law or rate equation for a chemical reaction is an equation that links the reaction rate with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reaction orders).
New!!: Elementary reaction and Rate equation · See more »
Reaction intermediate
A reaction intermediate or an intermediate is a molecular entity that is formed from the reactants (or preceding intermediates) and reacts further to give the directly observed products of a chemical reaction.
New!!: Elementary reaction and Reaction intermediate · See more »
Reaction rate
The reaction rate or rate of reaction is the speed at which reactants are converted into products.
New!!: Elementary reaction and Reaction rate · See more »
Reaction step
A reaction step of a chemical reaction is defined as: "An elementary reaction, constituting one of the stages of a stepwise reaction in which a reaction intermediate (or, for the first step, the reactants) is converted into the next reaction intermediate (or, for the last step, the products) in the sequence of intermediates between reactants and products".

Steady state (chemistry)
In chemistry, a steady state is a situation in which all state variables are constant in spite of ongoing processes that strive to change them.
New!!: Elementary reaction and Steady state (chemistry) · See more »
Stepwise reaction
A stepwise reaction is a chemical reaction with one or more reaction intermediates and involving at least two consecutive elementary reactions.
New!!: Elementary reaction and Stepwise reaction · See more »
Transition state
The transition state of a chemical reaction is a particular configuration along the reaction coordinate.
