Cov ib nrab - lub neej ntawm a tshuaj tiv thaiv yog lub sij hawm yuav tsum tau txo tus nqi ntawm ib tug muab reactant los ntawm ib- ib nrab . Cov ib nrab - lub neej ntawm a xoom - xaj tshuaj tiv thaiv txo qis raws li thawj zaug concentration ntawm cov reactant nyob rau hauv lub tshuaj tiv thaiv txo.
Xav txog qhov no, dab tsi yog qhov ib nrab lub neej rau kev txiav txim thawj zaug?
Cov ib nrab - lub neej ntawm ib qho tshuaj tshuaj tiv thaiv , tsis hais nws xaj , tsuas yog lub sijhawm xav tau rau ib nrab ntawm qhov pib concentration ntawm ib reactant yuav tsum tau noj los ntawm lub tshuaj tiv thaiv . Tam sim no, a ua ntej - xaj tshuaj tiv thaiv yog characterized los ntawm qhov tseeb hais tias tus nqi ntawm cov tshuaj tiv thaiv nyob ntawm linearly ntawm qhov concentration ntawm ib reactant.
Tsis tas li ntawd, 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.
Ib yam li ntawd, nws tau nug, ua li cas ib nrab lub neej ntawm xoom kev txiav txim cov tshuaj tiv thaiv cuam tshuam rau nws tus nqi tas li?
Li no, los ntawm qhov sib npaug saum toj no peb ua tau xaus tias cov ib nrab neej ntawm xoom xaj tshuaj tiv thaiv nyob ntawm thawj concentration ntawm reacting hom thiab cov tus nqi tas li , k. Nws yog ncaj qha proportional rau thawj concentration ntawm cov reactant whereas nws yog inversely proportional rau cov tus nqi tas li , ua k.
Vim li cas qhov kev txiav txim thawj zaug tsis ua tiav?
Yog li peb hais tau li ntawd thawj xaj tshuaj tiv thaiv yuav yeej tsis tiav los yog yuav ua tiav nyob rau lub sij hawm infinite thiab li no cov kab decay kab yuav yeej tsis ntsib x-axis. Rate tas li: Peb muab tau cov thawj xaj tus nqi txoj cai thiab los ntawm tus nqi qhia no thawj xaj tus nqi tsis tu ncua tuaj yeem muab tau.

Tus qauv ntawm xoom xaj tshuaj tiv thaiv yog dab tsi?
2 muaj daim ntawv ntawm algebraic equation rau ib txoj kab ncaj nraim, y = mx + b, nrog y = [A], mx = − kt, thiab b = [A] 0.) Hauv cov tshuaj tiv thaiv zeroth, tus nqi tas li yuav tsum muaj tib lub units raws li cov tshuaj tiv thaiv tus nqi, feem ntau moles ib liter ib ob
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
Yuav ua li cas ib nrab lub neej ntawm xoom txiav txim cov tshuaj tiv thaiv cuam tshuam rau nws tus nqi tas li?
Nyob rau hauv xoom-order kinetics, tus nqi ntawm cov tshuaj tiv thaiv tsis yog nyob ntawm seb lub substrate concentration. Tus qauv t 1/2 rau qhov kev txiav txim xoom qhia pom tias ib nrab-lub neej nyob ntawm tus nqi ntawm qhov pib concentration thiab tus nqi tas li
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
