A muab faib coefficient yog qhov piv ntawm cov concentration ntawm cov khoom hauv ib qho nruab nrab lossis theem (C1) mus rau qhov concentration nyob rau theem ob (C2) thaum ob qhov concentrations ntawm equilibrium; uas yog, muab faib coefficient = (C1/C2)sib npaug. Cov units ntawm C1 thiab C2 tej zaum yuav txawv.

Ib yam li ib tug yuav nug, koj ua li cas txiav txim siab qhov sib faib coefficient ntawm cov tshuaj?

Cov muab faib coefficient ntawm cov tshuaj tej zaum txiav txim siab los ntawm co nws nrog qhov sib npaug ntawm ob qhov sib npaug ntawm cov kuab tshuaj (cov organic txheej, uas yog saturated nrog dej, thiab cov aqueous. tshuaj daws) kom txog thaum muaj kev sib npaug. Cov ntsiab lus ntawm tshuaj nyob rau hauv ib qho ntawm cov txheej yog txiav txim siab thiab tus nqi raug xam.

Tsis tas li ntawd, dab tsi yog suav tias yog qhov sib faib siab coefficient? … unit of ntsuas hu ua muab faib coefficient .
