Qhov kev hloov pauv hauv lub zog dawb (ΔG) yog qhov sib txawv ntawm cov cua sov tso tawm thaum lub sijhawm ua haujlwm thiab cov cua sov tso tawm rau tib cov txheej txheem tshwm sim hauv qhov rov qab los. Yog hais tias ib qho kev sib npaug, ΔG=0.
Vim li cas Gibbs tsis muaj zog sib npaug ntawm xoom ntawm qhov sib npaug?
Gibbs lub zog tsis muaj zog yog qhov ntsuas qhov "muaj peev xwm" cov tshuaj tiv thaiv tau tso tseg los ua "ib yam dab tsi." Yog li yog tias lub zog pub dawb yog xoom, ces cov tshuaj tiv thaiv yog qhov sib npaug, tsis muaj haujlwm ntxiv tuaj yeem ua tiav Nws yuav yooj yim dua pom qhov no siv lwm daim ntawv ntawm Gibbs dawb lub zog, xws li ΔG=−TΔS.
Yuav ua li cas rau Gibbs dawb lub zog ntawm kev sib npaug?
Gibbs zog G yog qhov ntau uas dhau los ua qhov tsis zoo thaum lub sijhawm txheej txheem ntuj tsim. Yog li thaum muaj tshuaj lom neeg tshwm sim, G tsuas yog poob thiab yuav tsis zoo dua. … Ntawm no G yog qhov tsawg kawg nkaus (saib hauv qab), thiab tsis muaj kev hloov pauv ntxiv tuaj yeem tshwm sim; cov tshuaj tiv thaiv ces nyob rau hauv equilibrium.
Gibbs lub zog ntawm qhov sib npaug yog dab tsi?
Yog tias qhov system sib npaug, ΔG=0. Yog hais tias tus txheej txheem yog spontaneous, ΔG 0.
Puas yog Delta G 0 ntawm kev sib npaug?
Gibbs lub zog pub dawb yog lub zog pub dawb ua haujlwm. Ntawm qhov sib npaug, tsis muaj lub zog net tau txais lossis poob (tsis muaj dab tsi hloov pauv tiag tiag). Yog li, ntawm qhov sib npaug, Delta G yog 0.

Thaum lub zog kinetic yog lub zog muaj zog?
Tam sim no koj paub tias lub zog muaj peev xwm yog txoj haujlwm txheeb ze, thiab lub zog kinetic yog kev sib txheeb ze. Qhov tseem ceeb ntawm kev sib raug zoo ntawm ob yog lawv lub peev xwm los hloov mus rau ib leeg. Hauv lwm lo lus, lub zog muaj peev xwm hloov mus ua lub zog kinetic, thiab lub zog kinetic hloov mus ua lub zog muaj peev xwm, thiab rov qab los dua .
