Qhov Tseem Ceeb Qhov Sib Txawv - Qhov Sib Txawv Tsis Txaus Siab vs Equilibrium Position
Equilibrium tas li yog tus lej uas muab kev sib raug zoo ntawm cov khoom lag luam thiab cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv sib xyaw ntawm nws qhov sib npaug thaum qhov sib npaug yog lub sijhawm uas qhov sib npaug ntawm qhov sib npaug ntawm cov tshuaj tiv thaiv rov qab. Qhov no yog qhov sib txawv tseem ceeb ntawm qhov sib npaug tas li thiab qhov sib npaug.
Kev sib npaug yog lub xeev ntawm lub system uas muaj kev cuam tshuam rau pem hauv ntej thiab rov qab tib lub sijhawm. Qhov no txhais tau tias, muaj kev tawm tsam tawm tsam uas sib npaug sib npaug. Lub equilibrium tas mus li muab ib qho kev piav qhia ntawm qhov sib npaug ntawm lub xeev ntawm qhov system whereas equilibrium txoj hauj lwm piav qhia qhov sib npaug ntawm qhov system zoo.
Yuav ua li cas yog qhov Equilibrium?
Qhov sib npaug tas li yog tus lej uas muab kev sib raug zoo ntawm cov khoom lag luam thiab cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv sib xyaw ntawm nws qhov sib npaug. Ib qho kev sib npaug ntawm cov tshuaj tiv thaiv sib tov yog lub xeev mus txog los ntawm qhov system uas tsis muaj kev hloov pauv ntxiv ntawm cov reactants lossis cov khoom siv. Qhov sib npaug tas li yog qhov sib piv ntawm cov khoom lag luam thiab cov reactants.
Daim duab 01: Cov paib siv los qhia qhov sib npaug
Qhov sib npaug tas li yog ywj pheej ntawm thawj zaug ntawm cov reactants. Cov yam tseem ceeb uas cuam tshuam rau tus nqi ntawm qhov sib npaug tsis tu ncua yog qhov kub, qhov xwm txheej ntawm cov kuab tshuaj, lub zog ionic ntawm ions hauv cov tshuaj tiv thaiv sib tov, thiab lwm yam. Qhov sib npaug tas li yog qhia los ntawm "K"..
Equilibrium Constant Equation
A + B ↔ C
Rau cov tshuaj tiv thaiv saum toj no, qhov sib npaug tsis tu ncua tuaj yeem muab tau raws li hauv qab no.
K=[C]/ [A][B]
Qhov no tseem hu ua qhov sib npaug ntawm qhov sib npaug vim tias cov concentrations ntawm reactants thiab cov khoom siv los sau cov lus qhia. Nws yog denoted los ntawm Kc. Yog tias tus nqi ntawm K siab dua 1, qhov sib npaug nyiam cov khoom. Tab sis yog tias tus nqi ntawm K qis dua 1, qhov sib npaug nyiam cov tshuaj reactants. Thaum sau cov lus qhia ntawm qhov sib npaug tas li, yuav tsum xav txog qhov tseem ceeb ntawm qhov sib npaug.
aA + bB ↔ cC
K ntawm qhov sib npaug saum toj no yog raws li hauv qab no.
K=[C]c / [A]a[B]b
Rau qhov kev cuam tshuam ntawm cov khoom siv roj, qhov sib npaug tas li yog muab raws li qhov sib npaug ntawm qhov siab. Nws yog denoted los ntawm Kp. Nyob ntawd, lub siab ntawm cov pa roj yog txiav txim siab, thiab cov chav nyob ntawm qhov sib npaug tas li yog muab los ntawm cov chav nyob ntawm qhov siab.
Txoj haujlwm sib npaug yog dab tsi?
Equilibrium txoj hauj lwm yog lub sijhawm uas qhov kev sib npaug rau pem hauv ntej yog sib npaug ntawm cov tshuaj tiv thaiv rov qab. Tsis muaj kev hloov pauv hauv qhov system ntawm txoj haujlwm sib npaug. Tsis muaj tus nqi ntawm cov reactants yog qhov poob, lossis tsis muaj cov khoom tsim. Yog tias cov khoom raug tsim, lawv raug hloov dua siab tshiab rau hauv reactants thiab vice versa.
Dab tsi yog qhov txawv ntawm Equilibrium Constant thiab Equilibrium Position?

Summary – Equilibrium Constant vs Equilibrium Position
Qhov sib npaug tas li yog qhov kev piav qhia ntau ntawm qhov sib npaug ntawm qhov system whereas equilibrium txoj hauj lwm yog qhov kev piav qhia ntawm qhov sib npaug. Qhov sib txawv ntawm qhov sib npaug ntawm qhov sib npaug thiab qhov sib npaug yog qhov sib npaug tas li yog tus lej uas muab kev sib raug zoo ntawm cov khoom lag luam thiab cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv sib npaug ntawm nws qhov sib npaug thaum qhov sib npaug ntawm qhov sib npaug yog lub sijhawm uas qhov sib npaug ntawm qhov sib npaug ntawm qhov sib npaug. rov qab teb.
