Yog koj xav tau siv qhov no kev sib npaug , tsuas yog nrhiav "ln" khawm ntawm koj lub laij lej. Koj ua tau siv qhov sib npaug Arrhenius los qhia cov nyhuv ntawm qhov kev hloov ntawm qhov kub thiab txias ntawm tus nqi tas li - thiab yog li ntawm tus nqi ntawm cov tshuaj tiv thaiv. Yog hais tias tus nqi tas li doubles, piv txwv li, kuj yuav tus nqi ntawm cov tshuaj tiv thaiv.

Ib yam li ntawd, cov mis rau kev ua kom lub zog yog dab tsi?

Kev txiav txim siab ua kom muaj zog. Daim ntawv ceeb toom tias thaum Arrhenius equation yog rearranged li saum toj no nws yog ib tug linear kab zauv nrog rau daim ntawv y = mx + b; y yog ln(k), x yog 1/T, thiab m yog -Ea/R. Lub zog ua kom muaj zog rau cov tshuaj tiv thaiv tuaj yeem txiav txim siab los ntawm kev nrhiav tus txoj kab nqes ntawm kab.

Tsis tas li ntawd, cov units rau K yog dab tsi? Los ntawm tus qauv ntawm units peb tuaj yeem hais tias rau cov tshuaj tiv thaiv ntawm kinetic order n, the units ntawm k yog: k = 1/tc^(n-1), nco ntsoov tias c yog tus nqi ib liter qhia nyob rau hauv loj los yog molarity thiab n yog qhov kev txiav txim kinetic.

Tom qab ntawd, dab tsi yog cov units ntawm kev ua kom lub zog hauv Arrhenius equation?

qhov twg k sawv cev rau tus nqi tas li, Ea yog cov activation zog , R yog cov roj tsis tu ncua (8.3145 J / K mol), thiab T yog qhov ntsuas kub hauv Kelvin. A yog lub npe hu ua qhov frequency factor, muaj units ua L mol-1 s-1, thiab coj mus rau hauv tus account qhov zaus ntawm cov tshuaj tiv thaiv thiab qhov ua tau ntawm qhov tseeb molecular orientation.

Tus nqi tas li k yog dab tsi?

Cov tus nqi tas li , k , yog proportionality tas li uas qhia txog kev sib raug zoo ntawm molar concentration ntawm reactants thiab cov tus nqi ntawm ib qho tshuaj tiv thaiv. Cov tus nqi tas li tuaj yeem pom kev sim, siv cov molar concentrations ntawm cov reactants thiab qhov kev txiav txim ntawm cov tshuaj tiv thaiv.
