Activation zog yog tus nqi ntawm lub zog uas yuav tsum tau absorbed rau ib tshuaj tiv thaiv pib. Thaum lub zog ua kom txaus ntxiv rau cov reactants, daim ntawv cog lus nyob rau hauv cov reactants tawg thiab cov tshuaj tiv thaiv pib.

Ntawm no, daim ntawv cog lus ua li cas tawg thiab tsim thaum muaj tshuaj lom neeg?

Tshuaj tiv thaiv tso tawm los yog nqus zog. Lub zog uas ntxiv rau cov reactants tawg lawv chemical bonds . Thaum tshiab daim ntawv cog lus nyob rau hauv cov khoom, lub zog yog tso tawm. Qhov no txhais tau hais tias lub zog yog absorbed thiab tso tawm thaum ib tshuaj tiv thaiv . Ib txhia tshuaj tiv thaiv tso tawm ntau zog tshaj lawv nqus.

Qhov thib ob, daim ntawv cog lus tawg qhov twg? Lub tshav kub coj los yog muab tawm hauv cov tshuaj tiv thaiv los ntawm cov tshuaj daim ntawv cog lus ua los yog tawg hauv cov tshuaj tiv thaiv. Thaum lub sij hawm tshuaj tiv thaiv, Yog hais tias tag nrho lub zog yuav tsum tau tawg daim ntawv cog lus nyob rau hauv cov reactants yog ntau tshaj li tag nrho lub zog tso tawm thaum tshiab daim ntawv cog lus yog tsim nyob rau hauv cov khoom, nws yog ib tug endothermic cov tshuaj tiv thaiv.

Tom qab ntawd, lo lus nug yog, thaum twg ib daim ntawv cog lus tshuaj tawg yog lub zog?

Bond - tawg yog cov txheej txheem endothermic. Zog yog tso tawm thaum tshiab daim ntawv cog lus daim ntawv. Bond -ua yog txheej txheem exothermic. Seb cov tshuaj tiv thaiv yog endothermic los yog exothermic nyob ntawm qhov sib txawv ntawm cov zog yuav tsum tau tawg daim ntawv cog lus thiab cov zog tso tawm thaum tshiab daim ntawv cog lus daim ntawv.

Dab tsi ua rau cov tshuaj lom neeg tawg?

Bond zog yog tus nqi zog uas tawg ib daim ntawv cog lus . Zog ntxiv rau tawg daim ntawv cog lus thiab lub zog kuj tso tawm thaum daim ntawv cog lus daim ntawv. Nyob rau hauv ib qho exothermic cov tshuaj tiv thaiv, cov khoom muaj (ntau dua los yog tsawg) lub zog tshaj cov reactants.
