Cov pem hauv ntej cov tshuaj tiv thaiv muaj ΔH>0. Qhov no txhais tau tias cov pem hauv ntej cov tshuaj tiv thaiv yog endothermic . Rov qab tshuaj tiv thaiv yuav tsum yog li ntawd exothermic.
Ib yam li ntawd, koj yuav paub li cas yog tias qhov kev tawm tsam tom ntej yog endothermic lossis exothermic?
T tag nrho yog nyob ntawm hom NTAWM REACTION . IF LUB FORWARD REACTION YOG IB TUG TXIV NEEJ THIAB REACTION YOG ENDOTHERMIC . IF LUB FORWARDREACTION YOG IB TUG IB TUG PHIM NYUB VAIS TIAG REACTION YOG EXOTHERMIC . NTXIV: #An exothermic tshuaj tiv thaiv yog achemical tshuaj tiv thaiv uas tso cua sov.
Ib tug kuj yuav nug, qhov kub thiab txias cuam tshuam li cas rau exothermic tshua? Rau ib exothermic tshuaj tiv thaiv , tshav kub yog qhov tseem ceeb ntawm cov khoom tshuaj tiv thaiv . Ua raws li Le Chatelier'sprincipple, yog tias koj nce qhov kub koj tab tom nce tus nqi ntawm cov khoom, thiab yog li koj hloov qhov nyiaj tshuav atequilibrium rov qab mus rau reactants, txhais tau tias yuav muaj ntau dua reactants tshuav ntawm equilibrium.
Ib yam li ntawd ib tug yuav nug, hom tshuaj tiv thaiv dab tsi yog cov tshuaj tiv thaiv pem hauv ntej?
Cov tshuaj tiv thaiv pem hauv ntej yog a tshuaj tiv thaiv nyob rau hauv uas cov khoom yog tsim los ntawm reactants thiab nws mus ntawm sab laug mus rau sab xis nyob rau hauv ib tug reversible tshuaj tiv thaiv.
Puas yog qhov txo qis hauv qhov kub thiab txias endothermic lossis exothermic?
Hauv thawj cov tshuaj tiv thaiv, lub zog muab tawm tsis zoo thiab yog li cov tshuaj tiv thaiv yog exothermic . Txawm li cas los xij, anincrease nyob rau hauv kub tso cai rau lub cev kom nqus tau lub zog thiab yog li txaus siab rau ib qho endothermic tshuaj tiv thaiv; lub equilibrium yuav hloov mus rau sab laug.

Puas yog lub zog tso tawm lossis absorbed hauv cov tshuaj tiv thaiv exothermic?
Ib qho tshuaj tiv thaiv uas lub zog tawm mus rau ib puag ncig yog hu ua cov tshuaj tiv thaiv exothermic. Nyob rau hauv hom tshuaj tiv thaiv no lub enthalpy, los yog khaws cia chemical zog, yog qis dua rau cov khoom tshaj cov reactants. Thaum ammonium nitrate yaj nyob rau hauv dej, lub zog yog absorbed thiab dej txias
Puas yog cov tshuaj tiv thaiv combustion exothermic lossis endothermic?
Combustion yog ib qho oxidation cov tshuaj tiv thaiv uas ua rau kub, thiab nws yog li ntawd ib txwm exothermic. Tag nrho cov tshuaj tiv thaiv ua ntej tawg cov ntawv cog lus thiab tom qab ntawd ua cov tshiab los tsim cov ntaub ntawv tshiab. Kev rhuav tshem cov ntawv cog lus siv lub zog thaum ua cov ntawv cog lus tshiab tso tawm lub zog
Vim li cas cov tshuaj tiv thaiv kev zom zaub mov hu ua hydrolysis cov tshuaj tiv thaiv?
Thaum lub sij hawm zom mov, piv txwv li, decompositionreactions zom cov zaub mov loj rau hauv cov me me los ntawm kev ntxiv cov dej molecules. Hom tshuaj no hu ua hydrolysis. Raws li dej absorbs heatenergy, qee lub zog yog siv los rhuav tshem hydrogenbonds
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
