Cov tshuaj tiv thaiv Coordinate Diagrams . Cia peb xav txog cov tshuaj tiv thaiv dav dav uas cov tshuaj reactant lossis cov txheej txheem reactants, A, hloov mus rau hauv cov khoom lossis cov khoom lag luam, B. daim duab hauv qab no yog hu ua cov tshuaj tiv thaiv daim duab kos duab . Nws qhia tau hais tias lub zog ntawm lub cev hloov pauv li cas thaum muaj tshuaj tiv thaiv.

Ib yam li ntawd, nws raug nug, dab tsi yog kev sib koom tes sib koom tes txhais tau li cas?

Hauv chemistry, a kev sib koom tes yog abstract ib-dimensional koom tes uas sawv cev rau kev vam meej raws a tshuaj tiv thaiv txoj kev. Nws yog feem ntau yog ib qho kev ntsuas geometric uas hloov pauv thaum hloov pauv ntawm ib lossis ntau qhov chaw molecular.

Tom qab ntawd, lo lus nug yog, dab tsi yog daim duab enthalpy profile? Ib enthalpy daim duab cov ntaub ntawv hais txog cov tshuaj tiv thaiv xws li qib pib lub zog, yuav tsum muaj zog npaum li cas ntxiv los qhib cov tshuaj tiv thaiv, thiab lub zog kawg. Ib enthalpy daim duab yog graphed nrog cov enthalpy ntawm lub y-axis thiab lub sij hawm, los yog cov tshuaj tiv thaiv kev nce qib, ntawm x-axis.

Kuj paub yog, daim duab hluav taws xob yog dab tsi?

Cov duab kos duab piav qhia txog cov tshuaj tiv thaiv kev nce qib zog . Rau exothermic cov tshuaj tiv thaiv, cov reactants yog kos saum cov khoom vim lawv zog yog ntau dua. Yog li nyob rau hauv cov tshuaj tiv thaiv tshwj xeeb, qhov tshuaj tiv thaiv no tshwj xeeb.

Dab tsi yog A hauv Arrhenius equation?

Hais txog Kev Sau Ntawv. 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.
