Qhov sib txawv tseem ceeb ntawm cov catalytic thiab stoichiometric reagents yog cov catalytic reagents tsis tau noj thaum lub sijhawm cov tshuaj tiv thaiv, qhov stoichiometric reagents tau noj thaum lub sijhawm tshuaj tiv thaiv.
Catalytic reagents thiab stoichiometric reagents yog ob hom reactants nyob rau hauv ib qho tshuaj tiv thaiv. Catalytic reagents zoo dua rau stoichiometric reagents. Qhov no yog vim tias cov khoom siv tshuaj lom neeg ntawm cov tshuaj tiv thaiv tshwj xeeb yuav tsum tau tsim nyob rau hauv ib txoj kev uas thaum kawg ntawm cov tshuaj tiv thaiv, cov reactants ntawm cov tshuaj tiv thaiv yuav tsum tau tawg mus rau hauv me me degradation cov khoom uas tsis nyob rau hauv ib puag ncig.
Catalytic Reagents yog dab tsi?
Catalytic reagents yog cov tshuaj reactants tshwj xeeb cov tshuaj tiv thaiv uas tsis tau noj thaum lub sij hawm cov tshuaj tiv thaiv. Catalyst yog ib yam khoom uas tuaj yeem ua rau cov tshuaj tiv thaiv ntawm ib qho tshuaj tiv thaiv. 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 ntawd, cov tshuaj no rov siv dua, thiab peb tuaj yeem cais nws los ntawm cov tshuaj tiv thaiv sib xyaw kom siv nws rau lwm cov tshuaj tiv thaiv. Ntxiv mus, peb tsuas xav tau me me ntawm cov catalyst rau catalysis ntawm cov tshuaj tiv thaiv.
Daim duab 01: Cov Enzymes yog Bio-catalysts
Feem ntau, tshuaj tiv thaiv tshwm sim sai dua thaum muaj cov catalyst. Nws yog vim hais tias lub catalyst 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. Txawm li cas los xij, yog tias cov tshuaj txo qis cov tshuaj tiv thaiv, peb hu nws ua tus inhibitor.
Peb tuaj yeem faib cov catalysts ua homogeneous lossis heterogeneous catalysts. Yog hais tias nws yog homogeneous, nws txhais tau hais tias cov catalyst thiab reactants nyob rau tib theem ntawm cov teeb meem (piv txwv li, kua theem). 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.
Stoichiometric Reagents yog dab tsi?
Stoichiometric reagents yog cov tshuaj reactants hauv cov tshuaj tiv thaiv tshuaj uas tau noj thaum lub sijhawm cov tshuaj tiv thaiv. Yog li ntawd, ib qho stoichiometric reagent nquag koom nrog cov tshuaj tiv thaiv tshuaj. Vim qhov kev noj no, stoichiometric reagent tsis rov tsim dua tom qab ua tiav cov tshuaj tiv thaiv.
Daim duab 02: Txawv Reagents
Ntxiv mus, hom reagents no txawv ntawm catalytic reagents vim lawv tsis nce cov tshuaj tiv thaiv (tsis cuam tshuam rau lub zog ua kom muaj zog).
Qhov txawv ntawm Catalytic thiab Stoichiometric Reagents yog dab tsi?
Qhov sib txawv tseem ceeb ntawm catalytic thiab stoichiometric reagents yog cov catalytic reagents tsis tau noj thaum lub sij hawm cov tshuaj tiv thaiv, hos stoichiometric reagents tau noj thaum lub sij hawm cov tshuaj tiv thaiv. Yog li ntawd, catalytic reagents yog superior rau stoichiometric reagents. Ntxiv mus, catalytic reagents tuaj yeem txo qhov kev ua kom lub zog thaiv ntawm cov tshuaj tiv thaiv tshuaj, qhov stoichiometric reagents tsis tuaj yeem cuam tshuam rau lub zog ua kom muaj zog.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm cov catalytic thiab stoichiometric reagents.
Summary – Catalytic vs Stoichiometric Reagents
Catalytic reagents thiab stoichiometric reagents yog ob hom reactants nyob rau hauv ib qho tshuaj tiv thaiv. Qhov sib txawv tseem ceeb ntawm catalytic thiab stoichiometric reagents yog tias catalytic reagents tsis tau noj thaum lub sij hawm cov tshuaj tiv thaiv, hos stoichiometric reagents tau noj thaum lub sij hawm cov tshuaj tiv thaiv. Li no, catalytic reagents yog superior rau stoichiometric reagents.
