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.

Dab tsi yog qhov txawv ntawm daim ntawv cog lus lub zog thiab daim ntawv cog lus dissociation zog?
Qhov sib txawv tseem ceeb ntawm kev sib txuas ntawm lub zog thiab lub zog bonddissociation yog tias lub zog sib txuas yog qhov nruab nrab ntawm lub zog xav tau los rhuav tshem tag nrho cov kev sib txuas ntawm tib ob hom atoms nyob rau hauv ib qho chaw sib txuas whereas daim ntawv cog lus dissociation zog yog tus nqi ntawm cov hluav taws xob xav tau los rhuav tshem ib qho kev sib koom ua ke inhomolysis
Cov tshuaj tua kab mob twg thaiv cov kab mob protein ntau?
Tetracyclins yog ib hom tshuaj tua kab mob uas suav nrog cov thawj tetracycline nrog rau doxycycline thiab minocycline. Cov tshuaj tua kab mob no khi rau A qhov chaw ntawm 30s ribosome, tiv thaiv tRNA los ntawm kev nqa cov amino acids tshiab. Yog tias tRNA tsis tuaj yeem txuas mus rau ribosome, ces tsis muaj cov proteins tshiab tuaj yeem ua tau
Txoj kev faib cov ntaub ntawv twg muab cov ntaub ntawv sib npaug ntawm cov ntaub ntawv lossis cov kev tshuaj xyuas hauv txhua chav kawm cov ntaub ntawv?
Quantile. txhua chav kawm muaj cov yam ntxwv sib npaug. Ib qho kev faib tawm ntau yog zoo haum rau cov ntaub ntawv faib tawm. Quantile muab tib tus lej ntawm cov ntaub ntawv muaj nuj nqis rau txhua chav kawm
Cov tshuaj tiv thaiv dab tsi yog qhov tshuaj tiv thaiv neutralization?
Neutralization yog ib hom tshuaj tiv thaiv nyob rau hauv uas muaj zog acid thiab muaj zog puag react nrog ib leeg los tsim dej thiab ntsev
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
