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.
Ntxiv mus, dab tsi yog cov units ntawm tus nqi tas li rau qhov kev txiav txim thib ob?
Yog li ntawd, ob npaug ntawm qhov concentration ntawm A quadruplesthe cov tshuaj tiv thaiv . Rau qhov units ntawm tshuaj tiv thaiv yuav moles ib liter ib thib ob (M/s), cov units ntawm a thib ob - xaj tus nqi tas li yuav tsum bethe inverse (M. s−1).
Tsis tas li ntawd, qhov ntsuas qhov ntsuas ntawm cov tshuaj tiv thaiv yog dab tsi? Rau lub hom phiaj ntawm tus nqi kev sib npaug thiab kev txiav txim ntawm tshuaj tiv thaiv , cov tus nqi ntawm a tshuaj tiv thaiv yog ntsuas cov ntsiab lus ntawm ceev npaum li cas cov concentration ntawm ib qho ntawm cov reactants poob. Nws units ua mol dm-3s-1.
Ib yam li ntawd, tus nqi tsis tu ncua hauv thawj qhov kev txiav txim yog dab tsi?
k yog ua ntej - xaj tus nqi tas li , uas muaj units ntawm 1 / s. Tus txheej txheem ntawm kev txiav txim siab xaj ntawm a tshuaj tiv thaiv yog lub npe hu ua txoj kev pib tus nqi . Zuag qhia tag nrho xaj ntawm a tshuaj tiv thaiv yog cov sum ntawm tag nrho cov exponents ntawm cov ntsiab lus concentration nyob rau hauv lub tus nqi kev sib npaug.
Qhov kev txiav txim xoom yog dab tsi?
Kev txhais ntawm xoom - kev txiav txim : 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.

Dab tsi yog qhov kev txiav txim ntawm ecological hierarchy los ntawm qhov tsawg tshaj plaws mus rau loj?
Cov ntsiab lus ntawm cov koom haum hauv ecology suav nrog cov pej xeem, zej zog, ecosystem, thiab biosphere. Ib qho ecosystem yog tag nrho cov tsiaj nyob hauv ib cheeb tsam cuam tshuam nrog tag nrho cov abiotic qhov chaw ntawm ib puag ncig
Lub hom phiaj ntawm kev txiav txim siab ntawm ib qho kev sib npaug tas li yog dab tsi?
Lub hom phiaj ntawm qhov kev sim no yog txhawm rau txiav txim siab qhov sib npaug tsis tu ncua rau cov tshuaj tiv thaiv. Fe3+ + SCN. & rho tawm; ⇌ FeSCN2+ thiab saib seb qhov tas mus li yog qhov tseeb tib yam hauv qab sib txawv. tej yam kev mob
Qhov twg hauv qab no yog chav tsev raug rau qhov kev txiav txim thib ob tus nqi tas li?
Rau cov units ntawm cov tshuaj tiv thaiv tus nqi yog moles ib liter ib ob (M / s), cov units ntawm ib tug thib ob-order tus nqi tas li yuav tsum yog tus inverse (M−1·s−1). Vim hais tias cov units ntawm molarity tau qhia raws li mol / L, chav tsev ntawm tus nqi tas mus li tuaj yeem sau ua L (mol·s)
Dab tsi tuaj yeem siv los txiav txim siab tus nqi ntawm cov tshuaj tiv thaiv enzyme catalyzed?
Enzyme catalysis yog kuaj pom los ntawm kev ntsuas qhov pom ntawm cov khoom lossis ploj ntawm cov reactants. Txhawm rau ntsuas qee yam, koj yuav tsum muaj peev xwm pom nws. Enzyme assay yog cov kev ntsuam xyuas tsim los ntsuas kev ua haujlwm ntawm enzyme los ntawm kev ntsuas qhov kev hloov pauv hauv cov ntsiab lus ntawm cov tshuaj uas pom tau
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
