Dab tsi yog catalyst hauv tshuaj tiv thaiv?
A catalyst yog ib yam khoom uas ua kom tus nqi ntawm a tshuaj tiv thaiv tab sis tsis tau noj thaum lub sij hawm kawm ntawv tshuaj tiv thaiv . A catalyst yuav tshwm nyob rau hauv cov kauj ruam ntawm a tshuaj tiv thaiv mechanism, tab sis nws yuav tsis tshwm nyob rau hauv tag nrho tshuaj tiv thaiv (raws li nws tsis yog ib tug reactant los yog khoom).
