    The Portable Document Format (PDF) was created by Adobe Systems, introduced at the Windows and OS/2 Conference in January 1993 and remained a proprietary format until it was released as an open standard in 2008.

  4. 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 ...

    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.

    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.

  7. 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:

    English Historical Documents (EHD) is a series of publications of source material on English history by the academic publisher Eyre and Spottiswoode, now part of Oxford University Press. Some later volumes were published by Routledge. The original general editor was David C. Douglas, professor of history at the University of Bristol ...
