Catalysts ua kom tus nqi ntawm cov tshuaj tiv thaiv, tab sis lawv tsis hloov txoj hauj lwm ntawm qhov sib npaug ntawm cov tshuaj tiv thaiv. Yog tias tsis muaj cov catalyst koj cov tshuaj tiv thaiv yuav ua tiav (tag nrho rau cov khoom), txawm tias qeeb heev, ces yog, nyob rau hauv lub xub ntiag ntawm catalysts, cov reactants yuav tag nrho tig mus rau hauv cov khoom.
Puas catalyst cuam tshuam nrawm ntawm cov tshuaj tiv thaiv?
Tus tus nqi ntawm cov tshuaj tiv thaiv tuaj yeem nce ntxiv los ntawm kev ntxiv cov khoom siv catalystLub catalyst yog ib yam khoom uas ua rau muaj tshuaj lom neeg nce ntxiv tab sis nws tsis siv (tseem muaj tshuaj lom neeg. tsis hloov thaum kawg). Nws muab txoj hauv kev hloov pauv ntawm kev ua kom qis zog.
Puas catalyst ceev?
A catalyst nce tus nqi ntawm cov tshuaj tiv thaiv vim: Lawv muab lwm txoj hauv kev uas muaj lub zog ua kom qis dua. Qhov no txhais tau hais tias ntau cov khoom muaj lub zog ua kom muaj zog rau cov tshuaj tiv thaiv tshwm sim (piv rau tsis muaj cov catalyst) thiab yog li qhov ceev ntawm cov tshuaj tiv thaiv nce.
Tus catalyst puas tuaj yeem ua rau qeeb qeeb?
Catalysis yog qhov hloov pauv ceev (tus nqi) ntawm cov tshuaj tiv thaiv tshuaj vim yog kev pab los ntawm catalyst. … Cov catalysts uas qeeb cov tshuaj tiv thaiv yog hu ua negative catalysts, los yog inhibitors. Cov khoom uas ua rau kom cov catalysts nce ntxiv yog hu ua cov neeg txhawb nqa, thiab cov khoom uas ua rau cov catalysts deactivates hu ua catalytic lom.
Dab tsi yog qhov catalyst tshaj plaws?
Ntawm no yog tsib yam tshuaj catalysts siv nyob rau hauv kev lag luam tsim
