Lub laij lej no suav cov txiaj ntsig ntawm qhov kub thiab txias ntawm cov tshuaj tiv thaiv uas siv cov Arrhenius kev sib npaug. k = A* np(-Ea/ R * T) qhov twg k yog tus nqi coefficient, A yog a tas li , Ea yog lub zog ua kom muaj zog, R yog universal gas tas li , thiab T yog qhov kub thiab txias (hauv kelvin). R muaj tus nqi ntawm 8.314 x 10-3 kwm mol-1K-1.
Nyob rau hauv tas li ntawd, tus nqi ntawm Arrhenius yog dab tsi?
Cov tus nqi ntawm cov pa tas li , R, yog 8.31 J-1 mol-1.
Tom qab ntawd, lo lus nug yog, ua li cas koj pom Arrhenius tas li? Cov Arrhenius equation yog k = Ae^(-Ea/RT), qhov A yog qhov zaus los yog ua ntej exponential thiab e^(-Ea/RT) yog cov feem ntawm kev sib tsoo uas muaj zog txaus los teb (xws li, muaj zog ntau dua los yog sib npaug rau lub zog ua kom Ea) ntawm qhov kub thiab txias T.
Kuj Paub, Dab Tsi A hauv Arrhenius kab zauv txhais li cas?
Lus Cim: Cov Arrhenius equation yog qee zaum qhia tias k = Ae-E/RT qha k yog cov Tus nqi ntawm cov tshuaj tiv thaiv tshuaj, A yog qhov tas li nyob ntawm cov tshuaj koom nrog, E yog cov activation zog, R yog cov universal gas tas li, thiab T yog cov kub.
Vim li cas qhov kev sib npaug Arrhenius tseem ceeb?
Arrhenius equation yog li ntawd tseem ceeb vim tias nws tso cai rau peb suav nrog cov xwm txheej uas cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv uas peb tsis tuaj yeem pom ntawm cov cai lij choj, xws li: kub, muaj cov catalyst, lub zog thaiv, zaus thiab kev taw qhia ntawm kev sib tsoo …

Dab tsi yog qhov tsis tu ncua hauv algebra?
Tus nqi ruaj khov. Hauv Algebra, qhov tas li yog tus lej ntawm nws tus kheej, lossis qee zaum tsab ntawv xws li a, b lossis c los sawv cev rau tus lej. Piv txwv li: hauv 'x + 5 = 9', 5 thiab 9 yog qhov tsis tu ncua. Saib: Variable
Dab tsi yog qhov txawv ntawm kev tswj thiab qhov tsis tu ncua hauv kev tshawb fawb?
Qhov sib txawv ntawm qhov tsis tu ncua thiab Tswj Ib qhov hloov pauv tsis tu ncua tsis hloov. Ib qho kev tswj hwm qhov sib txawv ntawm lwm qhov kev hloov pauv, tab sis txhob txwm ua kom tas mus li thoob plaws qhov kev sim kom qhia txog kev sib raug zoo ntawm kev vam thiab kev ywj pheej
Dab tsi yog qhov tsis tu ncua hauv kev tshawb fawb?
Nkag mus. Lub sij hawm tas li tsuas yog hais txog qee yam uas tsis hloov pauv. Hauv kev txheeb cais, thiab kev tshawb fawb kev tshawb fawb tshwj xeeb, cov lus teb feem ntau tau piav qhia raws li qhov sib txawv ntawm qhov sib txawv, kwv yees lub ntsiab lus hais tias cov lus teb tsis tuaj yeem kwv yees nrog qhov tseeb
Puas yog tus ntiv tes yog qhov hloov pauv tsis tu ncua lossis tsis txuas ntxiv?
Kev hloov pauv tsis tu ncua yog qhov sib txawv, thiab cov no yog cov yam ntxwv ntawm caj ces hloov, xws li qhov siab, xim plaub hau, khau loj. Koj qhov siab, qhov hnyav, ntiv tes ntev thiab lwm yam, yuav tau hloov pauv hauv koj lub neej (nruam), tab sis koj hom ntshav, hom pob ntseg, ntiv tes thiab poj niam txiv neej, tsis txhob (tsis txuas ntxiv)
