Lub zog sib cais yog lub zog yuav tsum tau -tus txheej txheem endothermic-kom tawg ib daim ntawv cog lus thiab tsim ob qho atomic lossis molecular tawg, txhua tus muaj ib qho hluav taws xob ntawm tus khub qub. Yog li, daim ntawv cog lus ruaj khov heev muaj kev sib koom ua lag luam loj-lub zog ntau dua yuav tsum tau ntxiv kom tshem tawm daim ntawv cog lus.
Dab tsi yog qhov sib txawv ntawm lub zog sib cais thiab lub zog sib cog lus?
Qhov sib txawv tseem ceeb ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus lub zog yog qhov lub zog cog lus yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem txhua daim ntawv cog lus ntawm tib ob hom atoms hauv qhov sib xyaw whereas bond dissociation zog yog lub zog xav tau los rhuav tshem ib qho kev sib cog lus hauv homolysis.

Puas yog daim ntawv cog lus dissociation zog enthalpy?
Bond enthalpy (uas tseem hu ua daim ntawv cog lus-dissociation enthalpy, nruab nrab daim ntawv cog lus lub zog, lossis daim ntawv cog lus muaj zog) piav qhia tus nqi ntawm lub zog khaws cia hauv daim ntawv cog lus ntawm atoms hauv ib lub molecule. … Qhov siab dua ntawm daim ntawv cog lus enthalpy, lub zog ntau dua yog xav tau los rhuav tshem daim ntawv cog lus thiab qhov ruaj khov dua.
Vim li cas lub zog dissociation tseem hu ua lub zog nyiaj txiag?
Bond dissociation zog yog tsuas yog sib npaug ntawm daim ntawv cog lus zog rau diatomic molecules. Qhov no yogvim tias daim ntawv cog lus dissociation zog yog lub zog ntawm ib daim ntawv cog lus tshuaj, thaum daim ntawv cog lus lub zog yog qhov nruab nrab tus nqi rau tag nrho cov nyiaj sib koom ua ke ntawm txhua daim ntawv cog lus ntawm qee yam hauv ib lub molecule.

Tus neeg sau nyiaj txiag nrhiav dab tsi hauv cov ntawv teev nyiaj txiag?
Thaum cov neeg sau nyiaj txiag saib xyuas koj cov ntaub ntawv hauv txhab nyiaj, lawv xav pom tias koj muaj nyiaj txaus los them koj cov nqi them thiab kaw. Qee hom qiv nyiaj yuav tsum muaj ob peb lub hlis ntawm cov nqi tsev qiv nyiaj tshuav nyob rau hauv tus as-qhauj rau qhov xwm txheej "
Qhov twg tsis yog nyiaj txiag nqis peev thiab nyiaj txiag tshaj tawm?
A. Qhov tseem ceeb tsis yog nyiaj txiag thiab kev nqis peev nyiaj txiag tau tshaj tawm ntawm lub tuam txhab cov nyiaj tau los. Kev nqis peev uas tsis yog nyiaj thiab nyiaj txiag tau tshaj tawm li cas? Qhia tawm lossis Tshaj TawmHloov chaw, txhawm rau sau cov haujlwm tsis yog nyiaj ntsuab thiab nyiaj txiag, koj yuav tsum suav nrog cov lus hauv qab ntawm nqe lus ntawm cov nyiaj ntws los yog hauv cov ntawv sau ntawm cov ntaub ntawv nyiaj txiag.
Puas yog phooj ywg nyiaj txiag muaj kev nplua nyiaj ua ntej?
Q: Kuv daim ntawv cog lus hais Kuv tuaj yeem them ua ntej yam tsis raug nplua. … Los ntawm kev them nyiaj ntxiv thaum koj them koj cov nyiaj them poob haujlwm (thiab yog tias koj tsis tuaj yeem lig), koj yuav them tsawg dua cov nqi nyiaj txiag uas tau tshaj tawm hauv koj daim ntawv cog lus thiab koj yuav them koj tus as khauj sai dua.
