Nyob rau hauv ib qho tshuaj sib npaug, cov tshuaj tiv thaiv rau pem hauv ntej thiab thim rov qab Cov tshuaj tiv thaiv rov qab yog ib qho reaction uas hloov dua siab tshiab ntawm reactants rau cov khoom thiab hloov cov khoom rau reactants tshwm sim ib txhij … Hauv qhov rov qab cov tshuaj tiv thaiv, hydrogen iodide decomposes rov qab rau hauv hydrogen thiab iodine. Ob qhov kev tshwm sim tuaj yeem ua ke rau hauv ib qho kev sib npaug los ntawm kev siv ob lub xub. https://courses.lumenlearning.com › reversible-reaction

tshwm sim ntawm tus nqi sib npaug, thiab qhov ntau ntawm cov khoom thiab reactants nyob twj ywm. Lub catalyst ua kom tus nqi ntawm cov tshuaj tiv thaiv tshuaj, tab sis tsis muaj qhov cuam tshuam rau txoj haujlwm sib npaug rau qhov tshuaj tiv thaiv.
Puas yog qhov sib npaug ntawm qhov sib npaug?
Qhov piv ntawm cov khoom ntim rau cov reactant concentrations yog xam. Vim hais tias cov concentrations yog ntsuas ntawm equilibrium, qhov sib npaug tas li tseem zoo ib yam rau qhov muab tshuaj tiv thaiv ywj pheej ntawm thawj zaugconcentrations.
Yuav ua li cas cov concentrations ntawm cov reactants thiab cov khoom hloov nyob rau lub sij hawm ntawm equilibrium?
Cov concentrations ntawm reactants thiab cov khoom tsis hloov nrog lub sij hawm Qhov no tsis txhais hais tias cov concentrations ntawm cov reactants thiab cov khoom sib npaug tab sis hais tias lawv cov concentrations tsis hloov vim hais tias tom ntej thiab kev rov qab tshwm sim tshwm sim ntawm tus nqi sib npaug.
Thaum qhov sib npaug tau tsim cov concentrations ntawm cov reactants thiab cov khoom yuav tsum sib npaug?
Kaitlin L. Tsis yog, qhov concentration ntawm cov tshuaj reactants thiab cov khoom tsis tas yuav sib npaug hauv kev sib npaug sib luag. Equilibrium tshwm sim rau ib tug reversible tshuaj. Reversible txhais tau hais tias raws li reactants tsoo rau hauv ib leeg thiab ua khoom, cov khoom nws thiaj li sib sau ua ke thiab tsoo rau hauv lawv tus kheej, reacting rau reactants.
Yuav ua li cas qhov sib npaug ntawm cov reactants piv rau qhov sib npaug?
Qhov piv ntawm cov khoom rau cov tshuaj reactants yog tsawg dua qhov rau lub kaw lus ntawm qhov sib npaug - qhov concentration lossis qhov siab ntawm cov reactants ntau dua li qhov concentration lossis siab ntawm cov khoom. Vim tias cov tshuaj tiv thaiv zoo li mus txog qhov sib npaug, lub kaw lus hloov mus rau txoj cai los ua ntau yam khoom.
