Gibbs dawb lub zog yog qhov tsis zoo rau qhov tshwm sim tshwm sim (tsuas yog). Nws tuaj yeem ua tau zoo thiab, rau cov tshuaj tiv thaiv uas tsis yog tshwm sim.
txhais li cas thaum Gibbs tsis muaj zog yog qhov zoo?
Lub cim ntawm ΔG yuav hloov ntawm qhov zoo mus rau qhov tsis zoo (lossis lwm qhov) qhov twg T=ΔH / ΔS. Nyob rau hauv rooj plaub uas ΔG yog: qhov tsis zoo, cov txheej txheem yog qhov tshwm sim thiab tuaj yeem ua mus rau pem hauv ntej raws li tau sau tseg. Qhov zoo, cov txheej txheem yog tsis yog raws li sau tseg, tab sis nws tuaj yeem ua raws li tus kheej rov qab.
Koj puas tuaj yeem muaj Gibbs tsis muaj zog?
Yes, Gibbs dawb lub zog tuaj yeem ua tsis zoo lossis zoo lossis xoom.
Puas yog Delta G zoo lossis tsis zoo?
'Thaum cov txheej txheem endothermic, ΔHsystem > 0, thiab cov entropy ntawm lub kaw lus txo qis, ΔSsystem>0, kos npe ntawm ΔG yog qhov zoo ntawm txhua qhov kub.

Qhov txawv ntawm lub zog thiab lub zog yog dab tsi?
Raws li verbs qhov sib txawv ntawm energize thiab enervate yog energize yog kom invigorate, kom nquag nquag thaum enervate yog (lb) kom txo lub zog los yog lub zog; debilitate. lo lus Enervates txhais li cas? 1: txoov kev puas siab puas ntsws lossis kev coj ncaj nceesntawm.
Vim li cas lub zog muaj peev xwm tsis zoo thaum lub zog txaus nyiam?
Qhov no yog tus nqi tsis zoo rau ob qho laj thawj; lub zog ua yeeb yam ntawm lawv yog qhov txaus nyiam, thiab xoom ntawm lub zog muaj peev xwm yog nyob ntawm kev sib cais tsis kawg. Qhov no yog qhov tshwm sim tsis zoo yog tias lub zog ntawm ob tus nqi txaus nyiam(lawv tawm tsam) thiab qhov zoo yog tias nws ntxub (cov nqi zoo sib xws).
Thaum gibbs dawb zog yog 0?
Yog ΔG=0, the system is at equilibrium. Yog hais tias ΔG>0, cov txheej txheem tsis tshwm sim raws li sau tseg tab sis tshwm sim spontaneously nyob rau hauv lub rov qab kev taw qhia. Yuav ua li cas thaum Delta G yog xoom? Thaum Δ G=0 \Delta \text G=0 ΔG=0delta, pib ntawv, G, ntawv kawg, sib npaug, 0, lub kaw lus nyob rau hauv qhov sib npaug thiab qhov ntau ntawm cov khoom thiab reactants yuav nyob tas mus li.
Lub sijhawm kuv lub sijhawm dawb lossis thaum kuv lub sijhawm dawb?
yog li, qhov no txhais tau tias "thaum kuv lub sijhawm dawb" tsis siv ntauthiab koj muab "hauv kuv lub sijhawm dawb" ntau dua nyob rau qhov kawg ntawm kab lus. Piv txwv li: Kuv tau taug kev tus dev thaum kuv lub sijhawm dawb.
Puas lub zej zog climax txawv ntawm ib lub zej zog vam meej?
Lub zej zog climax txawv li cas ntawm lub zej zog vam meej? Lub zej zog climax yog qhov ruaj khov, kav ntev, txoj kev sib txuas ntawm ntau yam kab mob sib txawv. Lub zej zog successional yog ib theem ntawm cov txheej txheem successional. Koj nyuam qhuav kawm 20 nqe lus!
