  2. Molecularity - Wikipedia

    en.wikipedia.org/wiki/Molecularity

    A termolecular [4] [5] (or trimolecular) [6] reaction in solutions or gas mixtures involves three reactants simultaneously colliding, with appropriate orientation and sufficient energy. [4] However the term trimolecular is also used to refer to three body association reactions of the type:

  3. Talk:Molecularity - Wikipedia

    en.wikipedia.org/wiki/Talk:Molecularity

    Now I read the actual definition carefully as well by the strictist application this reaction is not a termolecular reaction but 2 bimolecular ones with the first reaction being reversible. This may be one where the common use of the term "termolecular" in gas kinetics is not strictly speaking the same as its definition here.

    Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...

  5. Elementary reaction - Wikipedia

    en.wikipedia.org/wiki/Elementary_reaction

    According to collision theory the probability of three chemical species reacting simultaneously with each other in a termolecular elementary reaction is negligible. Hence such termolecular reactions are commonly referred as non-elementary reactions and can be broken down into a more fundamental set of bimolecular reactions, [ 3 ] [ 4 ] in ...

  6. Molecule - Wikipedia

    en.wikipedia.org/wiki/Molecule

    The definition of the molecule has evolved as knowledge of the structure of molecules has increased. Earlier definitions were less precise, defining molecules as the smallest particles of pure chemical substances that still retain their composition and chemical properties. [ 13 ]

    By definition, it is the amount of energy gained by the charge of a single electron moved across an electric potential difference of one volt. electronegativity A chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. electronics

    Such a mechanism is consistent with the predominantly anti addition (>15:1 anti:syn for the example shown) of the hydrochlorination product and the termolecular rate law, Rate = k[alkyne] [HCl] 2. [8] [9] In support of the proposed alkyne-HCl association, a T-shaped complex of an alkyne and HCl has been characterized crystallographically. [10]
