Tshuaj kinetics , kuj hu ua tshuaj tiv thaiv kinetics , yog ceg ntawm lub cev chemistry uas muaj kev txhawj xeeb nrog kev nkag siab cov nqi ntawm cov tshuaj cov tshuaj tiv thaiv . Nws yog yuav tsum tau contrasted nrog thermodynamics, uas cuam tshuam nrog cov kev taw qhia nyob rau hauv uas ib tug txheej txheem tshwm sim tab sis nyob rau hauv nws tus kheej qhia tsis muaj dab tsi txog nws tus nqi.
Ua raws li qhov no, dab tsi yog cov tshuaj tiv thaiv kinetics thiab vim li cas lawv tseem ceeb?
Ib tug yog vim li cas qhov tseem ceeb ntawm kinetics yog tias nws muab pov thawj rau cov mechanisms ntawm tshuaj txheej txheem. Dhau li ntawm intrinsic scientific txaus siab, kev paub txog tshuaj tiv thaiv mechanisms yog kev siv tswv yim los txiav txim siab seb qhov twg yog txoj hauv kev zoo tshaj plaws los ua ib qho tshuaj tiv thaiv tshwm sim.
Ib yam li ntawd, kinetics siv rau dab tsi? Tshuaj kinetics yog kev kawm txog cov txheej txheem tshuaj thiab cov nqi ntawm cov tshuaj tiv thaiv. Qhov no suav nrog kev txheeb xyuas cov xwm txheej uas cuam tshuam rau kev ceev ntawm cov tshuaj tiv thaiv tshuaj, nkag siab txog cov tshuaj tiv thaiv thiab kev hloov pauv, thiab tsim cov qauv lej los kwv yees thiab piav qhia txog cov tshuaj tiv thaiv tshuaj.
koj pom cov kinetics ntawm cov tshuaj tiv thaiv li cas?
Kev tshwm sim tus nqi yog xam los ntawm tus qauv tus nqi = Δ [C] / Δt, qhov twg Δ [C] yog qhov kev hloov ntawm cov khoom concentration thaum lub sij hawm lub sij hawm Δt. Tus nqi ntawm tshuaj tiv thaiv tuaj yeem pom los ntawm kev saib qhov ploj ntawm cov reactant lossis cov tsos ntawm cov khoom dhau sijhawm.
Tus nqi tshuaj kinetics yog dab tsi?
tus nqi ( kinetics ) Kinetics : Tus nqi . Tshuaj Kinetics - Kev tshawb fawb ntawm cov tus nqi ntawm tshuaj cov tshuaj tiv thaiv. Tus nqi Cov tshuaj tiv thaiv - Qhov kev hloov hauv qhov concentration ntawm ib qho ntawm cov reactants (DX), thaum lub sij hawm muab lub sij hawm (Dt) Cov tshuaj tiv thaiv tus nqi maj mam txo qis thaum noj cov tshuaj reactants.

Cov txheej txheem ntawm lub teeb nyob ntawm cov tshuaj tiv thaiv yog dab tsi?
Lub luag haujlwm tag nrho ntawm cov tshuaj tiv thaiv lub teeb, thawj theem ntawm photosynthesis, yog hloov lub hnub ci zog rau hauv cov tshuaj siv hluav taws xob nyob rau hauv daim ntawv ntawm NADPH thiab ATP, uas yog siv nyob rau hauv lub teeb-yooj yim tshuaj tiv thaiv thiab roj sib sau ua ke ntawm qab zib molecules
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
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
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
