A catalyst ua kom muaj tshuaj lom neeg tshuaj tiv thaiv , tsis tau noj los ntawm cov tshuaj tiv thaiv . Nws nce lub tshuaj tiv thaiv tus nqi los ntawm kev txo qis lub zog ua kom a tshuaj tiv thaiv.

Hauv qhov no, dab tsi yog ob txoj hauv kev catalyst cuam tshuam rau cov tshuaj tiv thaiv tshuaj?

Cov ob lub ntsiab txoj kev catalysts cuam tshuam cov tshuaj tiv thaiv yog los ntawm kev tsim ib txoj hauv kev kom txo qis kev ua kom lub zog lossis los ntawm kev hloov pauv li cas tshuaj tiv thaiv tshwm sim.

Tsis tas li ntawd, nqe lus twg zoo tshaj plaws piav qhia txog qhov catalyst cuam tshuam li cas cov tshuaj tiv thaiv tshuaj? A catalyst "muab ib qho alternate tshuaj tiv thaiv txoj hauv kev nrog lub zog ua kom qis dua "(2) yog qhov tseeb. tshuaj tiv thaiv . Thaum a catalyst yog muab tso rau hauv lub system, nws ua rau lub kaw lus yuav tsum tau tsawg activation zog, ua tus tshuaj tiv thaiv mus sai dua.

Ntawm no, Catalysts ua kom ceev cov tshuaj tiv thaiv li cas?

A catalyst nce tus nqi ntawm cov tshuaj tiv thaiv vim: Lawv muab lwm txoj hauv kev siv 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.

Ib qho piv txwv ntawm catalyst yog dab tsi?

Tshuaj Catalysts Hydrogen peroxide yuav decompose rau hauv dej thiab oxygen gas. Ob lub molecules ntawm hydrogen peroxide yuav tsim ob lub molecules ntawm dej thiab ib lub molecule ntawm oxygen. A catalyst Cov poov tshuaj permanganate tuaj yeem siv los ua kom cov txheej txheem no.
