Cov tag nrho xaj ntawm tshuaj tiv thaiv yog cov sum ntawm tus neeg txiav txim ntawm tshuaj tiv thaiv ntawm cov reactants thiab nws ntsuas qhov rhiab heev ntawm cov tshuaj tiv thaiv hloov nyob rau hauv cov concentration ntawm tag nrho cov reactants. Tus kheej xaj ntawm tshuaj tiv thaiv thiab yog li ntawd cov tag nrho xaj ntawm tshuaj tiv thaiv tau txiav txim siab sim.
Ib yam li ntawd, koj ua li cas suav RDS ntawm kev tawm tsam?
Cov tus nqi txiav txim kauj ruam yog qhov qeeb tshaj plaws ntawm cov tshuaj tshuaj tiv thaiv uas txiav txim qhov ceev (tus nqi) uas lub zuag qhia tag nrho 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.
Tsis tas li ntawd, txoj cai tus nqi ntawm thawj kauj ruam yog dab tsi? Chemists feem ntau sau tshuaj sib npaug rau cov tshuaj tiv thaiv ib leeg kauj ruam , uas qhia tau hais tias tsuas yog cov tshuaj tiv thaiv cov txiaj ntsig. Yog tias thawj kauj ruam yog qhov qeeb tshaj plaws, thiab tag nrho cov tshuaj tiv thaiv yuav tsum tau tos rau nws, ces nws yog qhov tus nqi - txiav txim siab kauj ruam.
Ua raws li qhov no hauv kev txiav txim siab, dab tsi yog tag nrho cov tshuaj tiv thaiv?
Cov tag nrho cov tshuaj tiv thaiv tus nqi yog txiav txim los ntawm cov tus nqi ntawm cov kauj ruam mus txog (thiab suav nrog) cov kauj ruam qis tshaj plaws. Cov kauj ruam qeeb tshaj hauv a tshuaj tiv thaiv mechanism yog hu ua tus nqi kev txiav txim los yog tus nqi txwv kauj ruam. Rau peb piv txwv mechanism nyob rau hauv nqe lus dhau los, lub tus nqi limiting kauj ruam yog thawj theem pib.
Qhov kev txiav txim thawj zaug yog dab tsi?
A ua ntej - xaj tshuaj tiv thaiv yog a tshuaj tiv thaiv uas ua tiav ntawm tus nqi uas nyob ntawm linearly ntawm tsuas yog ib qho reactant concentration.

Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
Lub npe rau ib yam khoom tsim nyob rau hauv cov tshuaj tiv thaiv tshuaj yog dab tsi?
Cov tshuaj tiv thaiv tshuaj yog cov txheej txheem uas cov atoms tam sim no nyob rau hauv cov tshuaj pib rov ua kom muab cov tshuaj sib xyaw tshiab tam sim no hauv cov tshuaj tsim los ntawm cov tshuaj tiv thaiv. Cov tshuaj pib ntawm cov tshuaj tiv thaiv tshuaj hu ua reactants, thiab cov tshuaj tshiab uas tshwm sim hu ua cov khoom
Yam dab tsi tuaj yeem hloov pauv yog tias koj xav nce tus nqi ntawm cov tshuaj tiv thaiv tshuaj?
Cov yam ntxwv uas cuam tshuam rau cov tshuaj tiv thaiv yog: thaj tsam ntawm cov khoom reactant. concentration los yog siab ntawm ib tug reactant. kub. xwm ntawm cov reactants. muaj/tsis muaj catalyst
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
