Qhov sib txawv tseem ceeb ntawm catalyst thiab reagent yog cov catalysts tsis tau noj thaum lub sij hawm cov tshuaj tiv thaiv, hos reagents tej zaum yuav los yog tej zaum yuav noj thaum muaj tshuaj tiv thaiv.
Catalyst thiab regent yog ob lo lus tseem ceeb uas peb feem ntau siv hauv analytical chemistry los piav txog cov tshuaj tiv thaiv. Qee tus neeg kuj siv ob lo lus reagent thiab reactant interchangeably txawm tias muaj qhov sib txawv me ntsis ntawm lawv. Catalyst yog ib yam khoom uas muaj peev xwm ua kom cov tshuaj tiv thaiv ntawm ib qho tshuaj tiv thaiv, thaum reagent yog ib yam khoom los yog sib tov siv rau hauv tshuaj ntsuam xyuas lossis lwm yam tshuaj tiv thaiv.
Catalyst yog dab tsi?
Catalyst yog ib yam khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv kab mob ntau ntxiv. Cov txheej txheem ntawm kev nce cov tshuaj tiv thaiv yog "catalysis". Cov cuab yeej tshwj xeeb tshaj plaws ntawm cov catalyst yog tias cov tshuaj tiv thaiv tsis siv cov catalysts thaum lub sij hawm kev loj hlob ntawm cov tshuaj tiv thaiv. Txawm li cas los xij, cov tshuaj no ncaj qha koom nrog cov tshuaj tiv thaiv. Yog li, cov tshuaj no rov ua dua tshiab, thiab peb tuaj yeem cais nws los ntawm cov tshuaj tiv thaiv sib xyaw kom siv nws hauv lwm cov tshuaj tiv thaiv. Ntxiv mus, peb tsuas xav tau me me ntawm cov catalyst rau catalysis ntawm cov tshuaj tiv thaiv.
Feem ntau, tshuaj tiv thaiv tshwm sim sai dua thaum muaj cov catalyst. Nws yog vim tias cov tshuaj no tuaj yeem muab txoj hauv kev rau cov tshuaj tiv thaiv tshwm sim. Lwm txoj hauv kev ib txwm muaj lub zog ua kom qis dua li txoj hauv kev ib txwm muaj (uas tshwm sim thaum tsis muaj catalyst). Ntxiv mus, catalyst nyiam tsim ib qho nruab nrab nrog cov reactant, thiab nws rov tsim dua tom qab. Nyob rau hauv sib piv, yog hais tias ib tug tshuaj txo cov tshuaj tiv thaiv tus nqi, peb hu nws ib tug inhibitor.

Peb tuaj yeem faib cov catalysts ua homogeneous lossis heterogeneous catalysts. Yog tias nws yog homogeneous, nws txhais tau hais tias cov catalyst thiab reactants nyob rau tib theem ntawm cov teeb meem (piv txwv li cov theem ua kua). Ntawm qhov tod tes, yog tias cov catalyst nyob rau theem sib txawv ntawm cov reactants, ces nws yog heterogeneous catalyst. Ntawm no, gaseous reactants adsorbed rau ntawm cov khoom catalyst nto.
Reagent yog dab tsi?
A reagent yog ib yam khoom lossis sib tov siv rau hauv kev tshuaj xyuas tshuaj lossis lwm yam tshuaj tiv thaiv. Nws tuaj yeem yog ib qho catalyst, uas ua rau nce cov tshuaj tiv thaiv lossis cov tshuaj reactant uas tau noj thaum lub sijhawm tshuaj tiv thaiv.

Yog tsis yog, nws yuav tsis cuam tshuam nrog tshuaj lom neeg hauv txhua txoj kev. Piv txwv li, cov kuab tshuaj xws li dej tuaj yeem tsuas yog qhov nruab nrab rau cov tshuaj tiv thaiv tshuaj tab sis tsis yog cov tshuaj reactant noj thaum lub sij hawm tshuaj tiv thaiv los yog cov catalyst uas ua rau cov tshuaj tiv thaiv nce ntxiv. Tsis tas li ntawd, cov tshuaj reagents yog cov tebchaw lossis cov khoom sib xyaw.
Qhov txawv ntawm Catalyst thiab Reagent yog dab tsi?
Catalyst yog ib yam khoom uas tuaj yeem nce cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv tshwj xeeb, thaum reagent yog ib yam khoom lossis sib tov siv rau hauv kev tshuaj xyuas tshuaj lossis lwm yam tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm catalyst thiab reagent yog cov catalysts tsis tau noj thaum lub sij hawm tshuaj tiv thaiv, hos reagent tej zaum yuav los yog tej zaum yuav noj thaum lub sij hawm tshuaj tiv thaiv.
Ntxiv mus, qhov sib txawv ntxiv ntawm cov catalyst thiab reagent yog tias cov catalysts rov tsim dua tom qab ua tiav cov tshuaj tiv thaiv tshuaj, thaum cov tshuaj reagents tuaj yeem rov tsim dua tshiab. Qee qhov piv txwv rau catalysts muaj xws li hlau yog ib qho catalyst rau ammonia synthesis, zeolite yog ib qho catalyst rau racking ntawm roj av, thiab lwm yam
Summary – Catalyst vs Reagent
A catalyst yog ib yam khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv tshwj xeeb, thaum lub reagent yog ib yam khoom lossis sib tov siv rau hauv kev tshuaj xyuas tshuaj lossis lwm yam tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm catalyst thiab reagent yog cov catalysts tsis tau noj thaum lub sij hawm tshuaj tiv thaiv, hos reagent tej zaum yuav los yog tej zaum yuav noj thaum lub sij hawm tshuaj tiv thaiv.
