Ib tus catalyst ua kom cov tshuaj tiv thaiv kab mob, tsis tas siv cov tshuaj tiv thaiv. Nws nce cov tshuaj tiv thaiv los ntawm txo qis lub zog ua kom rau cov tshuaj tiv thaiv. … Nco ntsoov tias nrog cov catalyst, qhov nruab nrab kinetic zog ntawm cov molecules tseem zoo li qub tab sis lub zog yuav tsum tau txo qis (Daim duab 7.13).
Puas catalyst nce lossis txo tus nqi ntawm cov tshuaj tiv thaiv?
Kev cuam tshuam ntawm catalysts. Tus nqi ntawm tawm tsam tuaj yeem nce ntxiv los ntawm kev ntxiv ib qho khoom siv tsim nyog. Lub catalyst yog ib yam khoom uas nce tus nqi ntawm cov tshuaj tiv thaiv tshuaj tab sis nws tsis siv (tseem tshuaj tsis hloov thaum kawg). Nws muab txoj hauv kev hloov pauv ntawm kev ua kom qis zog.
Catalyst cuam tshuam li cas cov tshuaj tiv thaiv?
Catalysts yog cov tebchaw uas ua kom tus nqi ntawm cov tshuaj tiv thaiv. Catalysts ua kom nrawm tawm tsam los ntawm kev txo lub zog ntawm tus nqi-txheej hloov lub xeev. Catalysts tsis cuam tshuam rau lub xeev sib npaug ntawm cov tshuaj tiv thaiv.
Qhov twg catalyst txo tus nqi ntawm cov tshuaj tiv thaiv?
Catalysts feem ntau ua kom cov tshuaj tiv thaiv los ntawm kev txo lub zog ua kom lub zog lossis hloov cov tshuaj tiv thaiv. Enzymes yog cov proteins uas ua cov catalysts hauv cov tshuaj biochemical. Cov hom catalysts muaj xws li enzymes, acid-base catalysts, thiab heterogeneous (los yog nto) catalysts.
Yuav ua li cas tsis zoo catalyst txo tus nqi ntawm cov tshuaj tiv thaiv?
Cov catalysts tsis zoo yog qhov muaj txiaj ntsig los ua kom qeeb lossis nres qhov tsis xav tau. - Hauv qhov tsis zoo catalysis tus nqi ntawm cov tshuaj tiv thaiv txo qis los ntawm kev ua kom lub zog ua kom muaj zog. Yog li, tus naj npawb ntawm cov reactant molecules uas tau hloov mus rau hauv cov khoom txo qis thiab li no tus nqi ntawm cov tshuaj tiv thaiv txo.
