Molecularity . Cov molecularity ntawm cov tshuaj tiv thaiv yog txhais raws li tus naj npawb ntawm cov molecules los yog ions uas koom rau hauv tus nqi txiav txim kauj ruam. Ib txoj hauv kev uas ob hom reacting sib xyaw ua ke nyob rau hauv txoj kev hloov pauv ntawm tus nqi txiav txim siab yog hu ua bimolecular.
Ib yam li ib tug yuav nug, qhov kev txiav txim thiab Molecularity ntawm cov tshuaj tiv thaiv yog dab tsi?
Molecularity ntawm tshuaj tiv thaiv tuaj yeem txhais tau tias yog tag nrho cov kab mob reacting nyob rau hauv tus nqi txiav txim siab. Ntawm qhov tod tes, lub xaj ntawm tshuaj tiv thaiv yog qhov kev suav ntawm lub zog ntawm cov concentration ntawm cov reactant molecules nyob rau hauv tus nqi sib npaug ntawm tshuaj tiv thaiv.
Ib sab saum toj no, Molecularity muab piv txwv li cas? Qhov Simplest Case: Ib Qhov Kev Pom Zoo Tsis Zoo Ib yam li ntawd, ib kauj ruam tshuaj tiv thaiv tau hais tias muaj molecularity ntawm 1 yog tias tsuas yog ib qho molecule hloov mus rau hauv cov khoom. Peb hu qhov no yog ib qho tshuaj tiv thaiv tsis muaj zog. Ib piv txwv yog decomposition ntawm N2 O4. N2O4 (g) → 2NO2 (g)
Cov lus nug tseem yog, koj ua li cas txiav txim siab Molecularity ntawm cov tshuaj tiv thaiv?
Feem ntau, molecularity ntawm qhov yooj yim cov tshuaj tiv thaiv yog sib npaug ntawm cov lej ntawm cov molecules ntawm reactants koom nrog hauv qhov sib npaug stoichiometric kev sib npaug . Cov molecularity ntawm cov tshuaj tiv thaiv yog tus naj npawb ntawm reactant molecules koom nrog hauv ib kauj ruam ntawm cov tshuaj tiv thaiv.
Qhov kev txiav txim ntawm cov tshuaj tiv thaiv yog dab tsi?
Cov Kev txiav txim ntawm Kev tshwm sim hais txog lub zog dependence ntawm tus nqi ntawm qhov concentration ntawm txhua reactant. Yog li, rau thawj- xaj tshuaj tiv thaiv , tus nqi yog nyob ntawm qhov concentration ntawm ib hom. Cov xaj ntawm tshuaj tiv thaiv yog ib qho kev sim txiav txim siab parameter thiab tuaj yeem ua rau tus nqi feem.
