  2. Molecularity - Wikipedia

    en.wikipedia.org/wiki/Molecularity

    The kinetic order of any elementary reaction or reaction step is equal to its molecularity, and the rate equation of an elementary reaction can therefore be determined by inspection, from the molecularity. [1] The kinetic order of a complex (multistep) reaction, however, is not necessarily equal to the number of molecules involved.

  3. Hard and soft G - Wikipedia

    en.wikipedia.org/wiki/Hard_and_soft_G

    While c , which also has hard and soft pronunciations, exists alongside k (which always indicates a hard pronunciation), g has no analogous letter or letter combination which consistently indicates a hard g sound, even though English uses j consistently for the soft g sound (the rationale for the spelling change of "gaol" to "jail").

  4. Reaction mechanism - Wikipedia

    en.wikipedia.org/wiki/Reaction_mechanism

    An example of a simple chain reaction is the thermal decomposition of acetaldehyde (CH 3 CHO) to methane (CH 4) and carbon monoxide (CO). The experimental reaction order is 3/2, [4] which can be explained by a Rice-Herzfeld mechanism. [5] This reaction mechanism for acetaldehyde has 4 steps with rate equations for each step :

    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 ...

  8. Cycloaddition - Wikipedia

    en.wikipedia.org/wiki/Cycloaddition

    In this notation, a Diels-Alder reaction is a (4+2)cycloaddition and a 1,3-dipolar addition such as the first step in ozonolysis is a (3+2)cycloaddition. The IUPAC preferred notation however, with [i+j+...] takes electrons into account and not atoms. In this notation, the DA reaction and the dipolar reaction both become a [4+2]cycloaddition.
