Cov chav nyob rau kev suav fugacity yog mol m3, uas yog cua concentration units.

fugacity coefficient sau nws cov units yog dab tsi?

Tus fugacity coefficient yog 97.03 atm100 atm=0.9703 . Kev koom tes ntawm nonideality rau molar Gibbs lub zog ntawm cov roj tiag tiag yog sib npaug rau RT ln φ. Rau nitrogen ntawm 100 atm, Gm=Gm, id+ RT ln 0.9703, uas yog tsawg dua qhov zoo tagnrho tus nqi Gm, id vim muaj kev sib haum xeeb. rog.

Dab tsi yog qhov sib npaug rau fugacity?

Tus fugacity coefficient yog txhais raws li qhov piv ntawm fugacity / siab. Rau cov pa roj ntawm qhov tsis tshua muaj siab (qhov twg txoj cai roj zoo tagnrho yog qhov kwv yees zoo), fugacity yog kwv yees sib npaug ntawm qhov siab. Yog li, rau qhov zoo tagnrho roj, qhov ratio ϕ=f / P ntawm fugacity f thiab siab P (fugacity coefficient) yog sib npaug rau 1.

Koj ua li cas xam nitrogen fugacity?

Rau nitrogen ntawm 100 atm, fugacity coefficient yog 97.03 atm / 100 atm=0.9703. Rau cov roj zoo tagnrho, fugacity thiab siab sib npaug yog li 1. Lub fugacity yog ze ze rau qhov kev ua haujlwm thermodynamic. Rau cov pa roj, qhov kev ua haujlwm tsuas yog qhov fugacity faib los ntawm kev siv siab kom muab qhov tsis muaj nuj nqis.

Vim li cas lub tswv yim ntawm fugacity tau raug qhia?

Lewis qhia txog lub tswvyim los ntawm kev siv lub zog pub dawb G los sawv cevtus cwj pwm tiag tiag ntawm cov pa roj tiag tiag uas txawv ntawm lub tswv yim ntawm cov pa roj zoo tagnrho. Lub tswvyim no yog lub npe hu ua tswvyim ntawm Fugacity. Qhov kev sib npaug no siv tau rau txhua qhov roj av txawm tias zoo tagnrho lossis tsis zoo.
