sijhawm rau cov tshuaj tiv thaiv rov qab: Nco ntsoov tias qhov sib npaug tau mus txog thaum ob qho tib si nkhaus toj siab, thiab cov concentrations ntawm ob qho tib si reactants thiab cov khoom tsis hloov tom qab.
Nws yog dab tsi thaum lub kaw lus nce mus txog qhov sib npaug?
Ib lub cev nyob ntawm qhov sib npaug thaum tus nqi ntawm cov kev cuam tshuam rau pem hauv ntej thiab rov qab sib npaugYog tias cov tshuaj tiv thaiv ntxiv ntxiv tus nqi ntawm cov tshuaj tiv thaiv pem hauv ntej nce. Raws li tus nqi ntawm qhov rov qab cov tshuaj tiv thaiv pib tsis hloov pauv, qhov sib npaug zoo li hloov mus rau cov khoom, lossis sab xis, sab ntawm qhov sib npaug.
Yuav ua li cas sib npaug thaum lub kaw lus sib npaug?
Equilibrium point yog qhov taw tes uas tus nqi ntawm cov tshuaj tiv thaiv pem hauv ntej yog sib npaug ntawm tus nqi ntawm cov tshuaj tiv thaiv rov qab, yog li cov concentrations ntawm cov khoom thiab cov reactants nyob twj ywm tib yam thiab tsis hloov ib zaug. lawv mus txog equilibrium.
Koj paub li cas thaum lub kaw lus nce mus txog qhov sib npaug?
Q tuaj yeem siv los txiav txim siab qhov kev taw qhia twg qhov kev cuam tshuam yuav hloov mus txog qhov sib npaug. Yog tias K > Q, cov tshuaj tiv thaiv yuav mus tom ntej, hloov cov reactants rau hauv cov khoom. Yog tias K < Q, cov tshuaj tiv thaiv yuav mus rau qhov kev taw qhia rov qab, hloov cov khoom rau hauv cov tshuaj reactants. Yog Q=K ces lub kaw lus twb sib npaug.
Vim li cas equilibrium tas li tsis cuam tshuam los ntawm concentration?
Raws li cov lus piav qhia hauv nqe lus saum toj no, txoj haujlwm ntawm qhov sib npaug ntawm cov tshuaj tiv thaiv tsis yog nyob ntawm qhov pib concentrations thiab yog li tus nqi ntawm qhov sib npaug tas li yog qhov tsis tu ncua. … Qhov no yog vim qhov sib npaug txhais tau tias yog ib qho xwm txheej uas tshwm sim los ntawm tus nqi ntawm pem hauv ntej thiab thim rov qab reactions sib npaug
