Exothermic reactions Cov no yog cov tshuaj tiv thaiv uas hloov lub zog rau ib puag ncig (ie lub zog tawm ntawm cov tshuaj tiv thaiv, yog li lub npe exothermic). Lub zog feem ntau yog hloov pauv raws li lub zog cua sov, ua rau cov tshuaj tiv thaiv sib xyaw thiab nws ib puag ncig los ua kub.
Yuav ua li cas rau lub zog tso tawm los ntawm cov tshuaj tiv thaiv exothermic?
Exothermic cov tshuaj tiv thaiv Nyob rau hauv cov tshuaj tiv thaiv exothermic, tag nrho lub zog ntawm cov khoom yog tsawg dua tag nrho lub zog ntawm cov reactants. Yog li ntawd, qhov kev hloov pauv hauv enthalpy yog qhov tsis zoo, thiab heat tawm mus rau ib puag ncig.
Yuav ua li cas rau lub zog hauv cov tshuaj tiv thaiv exothermic thiab cov tshuaj tiv thaiv endothermic?
Lub zog yog siv los rhuav tshem cov ntawv cog lus hauv cov tshuaj reactants, thiab lub zog raug tso tawm thaum cov ntawv cog lus tshiab tsim hauv cov khoom. Cov tshuaj tiv thaiv kab mob endothermic nqus lub zog, thiab cov tshuaj tiv thaiv exothermic tso tawm lub zog. … Txawm hais tias muaj tshuaj lom neeg cov tshuaj tiv thaiv absorbs los yog tso tawm lub zog, tsis muaj tag nrho cov kev hloov pauv ntawm lub zog thaum lub sij hawm cov tshuaj tiv thaiv.
Puas tshem tawm cov tshuaj tiv thaiv kab mob tsis muaj zog?
Thaum cov txheej txheem feem ntau, lub zog hloov pauv ntawm lub kaw lus thiab ib puag ncig. Yog hais tias lub kaw lus poob ib tug npaum li cas ntawm lub zog, lub tib lub zog yog tau los ntawm ib puag ncig. … rau txheej txheem exothermic tsis zoo vim tias lub kaw lus poob cua sov.
Yuav ua li cas rau lub zog tso tawm los ntawm cov tshuaj tiv thaiv exothermiclus nug?
Yuav ua li cas rau lub zog tso tawm los ntawm cov tshuaj tiv thaiv exothermic? Nws tso rau hauv ib puag ncig. Nws nce qhov kub ntawm cov khoom.
