Qhov sib npaug tas li yog sib npaug rau tus nqi tas li rau cov tshuaj tiv thaiv pem hauv ntej muab faib los ntawm tus nqi tas li rau qhov rov qab cov tshuaj tiv thaiv rov qab Cov ntsiab lus tseem ceeb ntawm chemistry yog cov tshuaj lom neeg tshwm sim thaum cov tshuaj tiv thaiv ib leeg tsim cov khoom. Cov tshuaj tiv thaiv unidirectional no hu ua irreversible reactions, cov tshuaj tiv thaiv uas cov reactants hloov mus rau cov khoom thiab qhov twg cov khoom tsis tuaj yeem hloov mus rau cov reactants. https://chem.libretexts.org › Equilibria › Dynamic_Equilibria

Puas qhov sib npaug yuav tsum sib npaug?
Tsis tas li. Lub kaw lus ntawm qhov sib npaug yog tus cwj pwm los ntawm qhov tsis tu ncua reactant thiab cov khoom lag luam ntau, tab sis qhov tseem ceeb ntawm cov reactant thiab cov khoom lag luam concentrations lawv tus kheej yuav tsum tsis txhob sib npaug.
Puas equilibrium txhais tau tias cov nqi sib npaug?
Equilibrium yog thaum tus nqi ntawm cov tshuaj tiv thaiv pem hauv ntej sib npaug tus nqi ntawm qhov rov qab. Tag nrho cov reactant thiab cov khoom concentration yog tas li ntawm qhov sib npaug.
Tus nqi tas li cuam tshuam li cas qhov sib npaug tsis tu ncua?
Kev piav qhia: Tsis muaj kev sib raug zoo ntawm tus nqi ntawm cov tshuaj tiv thaiv thiab qhov sib npaug tas li. Qhov tsuas yog qhov cuam tshuam rau qhov sib npaug tsis tu ncua yog qhov kub. Kev qhia dav dav ntawm cov tshuaj tiv thaiv tus nqi yog:R=k [Reactant]n thiab k ntawm no yog tus nqi tas mus li thiab tsis yog qhov sib npaug tsis tu ncua.
Yam dab tsi tsis cuam tshuam rau kev sib npaug?
Tom qab qhov sib ntxiv ntawm cov roj inert thiab nrog lub ntim cia tas li, tsis muaj kev cuam tshuam rau qhov sib npaug. Qhov no yog vim hais tias, ntawm qhov ntim tas li, qhov sib ntxiv ntawm cov roj inert tsis hloov ib nrab siab lossis molar concentration.
