Thaum muaj tshuaj tshuaj tiv thaiv siv qhov chaw zog yog coj los yog tso tawm. Hauv ib exergonic cov tshuaj tiv thaiv , lub zog raug tso tawm rau ib puag ncig. Cov ntawv cog lus raug tsim muaj zog dua li cov ntawv cog lus tau tawg. Hauv ib endergonicreaction , lub zog yog absorbed los ntawm cov puag ncig.

Xav txog qhov no, cov piv txwv ntawm endergonic thiab exergonic cov tshuaj tiv thaiv yog dab tsi?

Piv txwv ntawm exergonic cov tshuaj tiv thaiv suav nrog exothermic cov tshuaj tiv thaiv , xws li sib tov sodium thiab chlorine tomake lub rooj ntsev, combustion, thiab chemiluminescence (lub teeb yog theenergy uas tso tawm). Yog hais tias qhov kub thiab txias ntawm ib puag ncig increases, lub tshuaj tiv thaiv yog exothermic.

Ib yam li ntawd, nws txhais li cas los ua Endergonic? Ib endergonic tshuaj tiv thaiv (xws li photosynthesis) yog ib qho tshuaj tiv thaiv uas yuav tsum tau muaj zog tsav. Endergonic (los ntawm prefix endo-, muab los ntawm Greek lo lus ?νδον endon, "hauv", thiab lo lus Greek?ργον ergon, "ua haujlwm") txhais tau tias "absorbingenergy nyob rau hauv daim ntawv ntawm kev ua hauj lwm." Endergonic cov tshuaj tiv thaiv yog tsis raws cai.

Tib neeg kuj nug, qhov exergonic cov tshuaj tiv thaiv txhais li cas?

Ib exergonic cov tshuaj tiv thaiv hais txog a tshuaj tiv thaiv qhov twg zog yog tso tawm. Vim tias cov reactants poob zog (G txo qis), Gibbs dawb zog (ΔG) yog negative nyob rau qhov kub thiab txias. Cov no cov tshuaj tiv thaiv feem ntau ua tsis xav tau lub zog mus ntxiv, thiab yog li ntawd tshwm sim spontaneously.

Dab tsi yog qhov tseem ceeb ntawm kev muaj cov tshuaj tiv thaiv exergonic hauv lub cev?

Exergonic cov tshuaj tiv thaiv tso tawm lub zog uas yog khaws cia rau hauv daim ntawv cog lus ntawm cov molecules koom nrog hauv tshuaj tiv thaiv , thiab tso tawm spontaneously. Los ntawm muaj, nws tuaj yeem siv los ntawm cov tshuab sib txawv, txawm tias nws yog tus lub cev ormachinery, xws li lub tsheb, kom muaj zog rau lub hom phiaj muaj nuj nqi.
