Rau qhov units ntawm cov tshuaj tiv thaiv tus nqi yuav moles ib liter ib thib ob (M/s), cov units ntawm a thib ob - xaj tus nqi tas li yuav tsum yog inverse (M−1·s−1). Vim lub units Qhov ntsuas ntawm molarity yog qhia raws li mol / L chav tsev ntawm tus nqi tas li tuaj yeem sau ua L(mol·s).
Tib neeg kuj nug, dab tsi yog cov units ntawm tus nqi tas li rau qhov kev txiav txim thib ob?
Ob qho tib si reactant (A) ua ke hauv ib kauj ruam theem pib. qha k a thib ob xaj tus nqi tas li nrog units ntawm M -1 min -1 los yog M -1 s -1. Yog li ntawd, ob npaug ntawm qhov concentration ntawm reactant A yuav quadruple tus nqi ntawm tshuaj tiv thaiv.
Tom qab ntawd, lo lus nug yog, dab tsi yog units rau tus nqi tas li qhov kev txiav txim thib peb? Yog tias tshuaj tiv thaiv yog peb xaj , cov tus nqi tas li yuav tsum muaj units ntawm L2 mol-2 s-1.
Tsis tas li ntawd, dab tsi yog cov units rau tus nqi tsis tu ncua ntawm thawj qhov kev txiav txim thiab qhov kev txiav txim thib ob?
Hauv thawj qhov kev txiav txim , cov cov tshuaj tiv thaiv yog ncaj qha proportional rau cov reactant concentration thiab cov units ntawm thawj tus nqi tsis tu ncua yog 1/sec. Hauv bimolecular cov tshuaj tiv thaiv nrog ob reactants, lub thib ob kev txiav txim tus nqi tsis tu ncua muaj units ntawm 1 / M * sec.
Qhov kev txiav txim xoom yog dab tsi?
Kev txhais ntawm xoom - xaj tshuaj tiv thaiv : ib chemical tshuaj tiv thaiv uas tus nqi ntawm tshuaj tiv thaiv yog tas li thiab ywj siab ntawm cov concentration ntawm cov tshuaj reacting - piv xaj ntawm a tshuaj tiv thaiv.

Yuav ua li cas yog tus qauv chav tsev ntawm lub sij hawm thib ob txhais nyob rau hauv lub International System of Units?
Qhov thib ob (symbol: s, abbreviation: sec) yog lub hauv paus chav tsev ntawm lub sij hawm nyob rau hauv lub International System of Units (SI), feem ntau to taub thiab keeb kwm txhais tau tias yog ?1 ⁄ 86400 ntawm ib hnub - qhov tseem ceeb no tau los ntawm kev faib hnub. thawj zaug rau hauv 24 teev, ces mus rau 60 feeb thiab thaum kawg mus rau 60 vib nas this txhua
Qhov twg hauv qab no yuav tsum tau ntsib rau kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv tus nqi tuav?
Qhov twg hauv qab no yuav tsum tau ntsib rau kev sib tsoo txoj kev xav ntawm cov tshuaj tiv thaiv tus nqi tuav? - Lub reacting molecules yuav tsum sib tsoo nrog ib leeg. - Cov molecules yuav tsum sib tsoo nyob rau hauv ib qho kev taw qhia uas tuaj yeem ua rau rov kho cov atoms. -Cov reacting molecules yuav tsum sib tsoo nrog lub zog txaus
Qhov twg hauv qab no yog ib chav tsev rau hluav taws xob hluav taws xob?
Chav tsev rau hluav taws xob lub zog yog joule. Lub zog hluav taws xob rau lub zog yog watt. Cov mis laij lej hluav taws xob ces yog cov qauv hauv qab no. Lub zog hluav taws xob tau nthuav tawm hauv joules, lub zog yog qhia hauv watts, thiab lub sijhawm qhia hauv vib nas this
Dab tsi yog units ntawm tus nqi tas li rau thawj qhov kev txiav txim siab?
Hauv thawj qhov kev txiav txim siab, cov tshuaj tiv thaiv tus nqi yog ncaj qha rau cov reactant concentration thiab cov units ntawm firstorder tus nqi tas mus li yog 1 / sec. Hauv cov tshuaj tiv thaiv bimolecular nrog tworeactants, qhov kev txiav txim thib ob tus nqi tsis tu ncua muaj units ntawm 1 / M * sec
Yuav ua li cas koj txiav txim siab uas yog tus nqi txiav txim kauj ruam?
Tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws ntawm cov tshuaj tiv thaiv tshuaj uas txiav txim siab qhov nrawm (tus nqi) uas tag nrho cov tshuaj tiv thaiv ua tiav. Teb Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb. 2NO + 2H2 → N2 + 2H2O. Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O
