Exergonic cov tshuaj tiv thaiv koom nrog ionic bonds; endergonic cov tshuaj tiv thaiv koom nrog covalent bonds. Hauv exergonic cov tshuaj tiv thaiv , cov reactants muaj tshuaj muaj zog tsawg dua cov khoom; hauv endergonic cov tshuaj tiv thaiv , qhov opposite yog muaj tseeb. Exergonic cov tshuaj tiv thaiv koom nrog kev tawg ntawm daim ntawv cog lus; endergonic cov tshuaj tiv thaiv koom nrog kev tsim cov ntawv cog lus.

Nyob rau hauv txoj kev no, qhov txawv ntawm qhov exergonic cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv endergonic yog dab tsi?

Hauv exergonic cov tshuaj tiv thaiv lub zog dawb ntawm cov khoom yog qis dua li ntawm cov reactants; lub caij no hauv endergonic lub zog dawb ntawm cov khoom yog siab dua li ntawm cov reactants. Lub tsev ntawm complex molecules, xws li suab thaj, los ntawm cov yooj yim sawv daws yuav yog ib tug txheej txheem anabolic thiab yog endergonic.

Tsis tas li ntawd, dab tsi yog qhov exergonic quizlet? exergonic cov tshuaj tiv thaiv . ib tug spontaneous tshuaj tshuaj tiv thaiv , nyob rau hauv uas muaj ib tug net tso tawm dawb zog. endergonic tshuaj tiv thaiv . cov tshuaj uas tsis yog-spontaneous tshuaj tiv thaiv , nyob rau hauv uas lub zog dawb yog absorbed los ntawm ib puag ncig. ATP (adenosine triphosphate)

Tsis tas li ntawd, hom tshuaj tiv thaiv twg yog Endergonic?

Piv txwv ntawm endergonic cov tshuaj tiv thaiv suav nrog endothermic cov tshuaj tiv thaiv , xws li photosynthesis thiab melting ntawm dej khov rau hauv dej. Yog hais tias qhov kub ntawm ib puag ncig txo qis, lub tshuaj tiv thaiv yog endothermic.

Vim li cas qhov endergonic cov tshuaj tiv thaiv yog suav tias yog Nonspontaneous?

Ib endergonic cov tshuaj tiv thaiv (xws li photosynthesis) yog a tshuaj tiv thaiv uas yuav tsum tau lub zog tsav. Cov tshuaj tiv thaiv endergonic yog tsis raws cai . Kev vam meej ntawm cov tshuaj tiv thaiv yog qhia los ntawm kab. Kev hloov ntawm Gibbs dawb zog (ΔG) thaum lub sij hawm ib endergonic cov tshuaj tiv thaiv yog tus nqi zoo vim lub zog tau txais (2).
