Cov tus nqi ntawm ib qho tshuaj tshuaj tiv thaiv yog, kab tias, nws feem ntau tseem ceeb khoom vim nws dictates txawm tias a tshuaj tiv thaiv tuaj yeem tshwm sim hauv lub neej. Paub txog tus nqi kev cai lij choj, ib qho kev nthuav qhia ntsig txog cov tus nqi mus rau lub concentrations ntawm reactants, tuaj yeem pab tus kws kho mob kho cov tshuaj tiv thaiv tej yam kev mob kom tau ib tug ntau haum tus nqi.
Ntawm no, vim li cas tus nqi ntawm cov tshuaj tiv thaiv tseem ceeb hauv kev lag luam?
Cov tus nqi ntawm ib qho tshuaj tshuaj tiv thaiv qhia ushow ceev reactants hloov mus rau hauv cov khoom. Paub thiab tswj cov tus nqi ntawm cov tshuaj tiv thaiv yog tseem ceeb nyob hauv cov hlwb thiab kev lag luam . Nyob rau hauv lub cev tshuaj cov tshuaj tiv thaiv yuav tsum muaj qhov tseeb tus nqi muab koj cov cell nrog raws nraim qhov lawv xav tau thaum lawv xav tau.
Ib sab saum toj no, tus nqi ntawm cov tshuaj tiv thaiv txhais li cas? Cov cov tshuaj tiv thaiv los yog tus nqi ntawm cov tshuaj tiv thaiv yog qhov ceev ntawm reactants hloov dua siab tshiab rau hauv cov khoom. Rau feem ntau cov tshuaj tiv thaiv , cov tus nqi txos li cov tshuaj tiv thaiv ua tiav. Chemical kinetics yog ib feem ntawm lub cev chemistry uas kawm cov tshuaj tiv thaiv.
Tsis tas li ntawd, vim li cas tus nqi ntawm cov tshuaj tiv thaiv qeeb?
Rau ib tug muab tshuaj tiv thaiv , ceev ceev tshuaj tiv thaiv yuav sib txawv nrog qhov kub, qhov siab, thiab tus nqi ntawm cov reactants tam sim no. Cov tshuaj tiv thaiv feem ntau qeeb raws li lub sij hawm mus vim yog depletion ntawm thereactants.
Cov tshuaj tiv thaiv kinetics yog dab tsi thiab vim li cas lawv tseem ceeb?
Ib qho yog vim li cas qhov tseem ceeb ntawm kinetics yog hais 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 txiav txim siab dab tsi yog txoj hauv kev zoo tshaj plaws los ua ib qho tshuaj tiv thaiv tshwm sim.

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 ntxiv tus inhibitor cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv?
Kev piav qhia: Los ntawm txhais, inhibitors qeeb cov tshuaj tiv thaiv. Yog li ntawd, yog tias koj yuav tsum ntxiv ib qho inhibitor rau cov tshuaj tiv thaiv, koj yuav ua rau tus nqi ntawm cov tshuaj tiv thaiv txo. Cov tshuaj no ceev cov tshuaj tiv thaiv, yog li nce cov tshuaj tiv thaiv
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
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
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
