A catalyst ua kom muaj tshuaj lom neeg tshuaj tiv thaiv , tsis tau noj los ntawm cov tshuaj tiv thaiv . Nws nce lub cov tshuaj tiv thaiv los ntawm kev txo qis lub zog ua kom muaj zog rau a tshuaj tiv thaiv . Cov duab hluav taws xob muaj txiaj ntsig zoo los piav qhia qhov cov nyhuv ntawm ib tug catalyst ntawm cov tshuaj tiv thaiv.
Hauv qhov no, dab tsi yog qhov cuam tshuam ntawm catalyst ntawm lub zog ua kom muaj zog?
Catalysts muab txoj kev tawm tsam tshiab uas muaj qhov qis dua AE. A catalyst nce tus nqi ntawm cov tshuaj tiv thaiv los ntawm kev txo qis activation zog kom ntau reactant molecules tsoo nrog txaus zog kom dhau qhov me me zog thaiv.
Qhov thib ob, dab tsi yog qhov cuam tshuam ntawm catalyst ntawm cov tshuaj tiv thaiv chegg? A catalyst ib txwm txo qis enthalpy ntawm tshuaj tiv thaiv . A catalyst hloov enthalpy ntawm tshuaj tiv thaiv , txawm nce los yog txo nws. A catalyst txo tus nqi ntawm cov pem hauv ntej tshuaj tiv thaiv . A catalyst tsis hloov tus nqi rau pem hauv ntej tshuaj tiv thaiv.
Tsuas yog li ntawd, Catalysts ua kom cov tshuaj tiv thaiv sai li cas?
A catalyst nce tus nqi ntawm cov tshuaj tiv thaiv vim: Lawv muab txoj hauv kev hloov hluav taws xob uas muaj lub zog ua kom qis dua. Qhov no txhais tau hais tias ntau cov khoom muaj qhov ua kom lub zog xav tau rau lub tshuaj tiv thaiv coj qhov chaw (piv rau tsis muaj catalyst ) thiab lwm yam ceev ntawm tshuaj tiv thaiv nce.
Dab tsi cuam tshuam tus catalyst rau stoichiometry ntawm cov tshuaj tiv thaiv?
Nws feem ntau khi rau cov reactant thiab orients cov reactants optimally kom ceev cov tshuaj tiv thaiv . 2d ib. Dab tsi cuam tshuam tus catalyst muaj nyob rau ntawm stoichiometry ntawm cov tshuaj tiv thaiv ? Zuag qhia tag nrho stoichiometry ua tsis hloov vim lub catalyst tsis siv los yog tsim nyob rau hauv lub tshuaj tiv thaiv.
