Lub tswv yim ntawm catalysis
Catalysis, lub luag haujlwm ntawm cov catalyst hauv kev siv tshuaj lom neeg. Hauv catalytic cov tshuaj tiv thaiv, tus catalyst cov tshuaj lom neeg ua haujlwm nrog cov reactants, hloov kev hloov pauv cov kev coj ua, thiaj li txo qis kev ua kom lub zog ntawm kev tawm tsam.
Qhov tshwm sim ntawm kev ua kom nrawm lossis qeeb qeeb tawm ntawm tus nqi ntawm cov tshuaj tiv thaiv vim muaj kev cuam tshuam ntawm cov catalyst hu ua catalysis. Hauv catalytic cov tshuaj tiv thaiv, tus catalyst cov tshuaj lom neeg ua haujlwm nrog cov reactants, hloov cov tshuaj tiv thaiv kab ke, thiaj li txo qis kev ua kom lub zog ntawm kev tawm tsam, uas yog qhov laj thawj vim li cas cov catalyst tuaj yeem nce cov tshuaj tiv thaiv. Piv txwv li, tshuaj lom neeg cov tshuaj tiv thaiv A + B → AB, qhov yuav tsum ua kom muaj zog yog E. Tom qab ntxiv ntawm catalyst C, qhov tshuaj tiv thaiv yog nqa tawm hauv ob kauj ruam, thiab qhov yuav tsum tau ua kom lub zog yog F, G, ntsig txog, nyob rau F thiab G ob leeg me dua E.
