Chav tsev
- Rau kev txiav txim (m + n), lub tus nqi tas li muaj units ofmol·L·s−1
- Rau kev txiav txim xoom, lub tus nqi tas li muaj units ofmol · L−1·s−1(los yog M·s−1)
- Rau kev txiav txim ib, lub tus nqi tas li muaj units ntawm−1
- Rau kev txiav txim ob, lub tus nqi tas li muaj units ntawm L·mol−1·s−1(orM−1·s−1)
Ua kom pom qhov no, qhov ntsuas qhov ntsuas qhov tsis tu ncua yog dab tsi?
Cov tus nqi tas li yog proportionality tas li qhov twg tus nqi ntawm cov tshuaj tiv thaiv ncaj qha mus rau qhov concentration ntawm cov reactant. Nyob rau hauv thawj orderreactions, cov tshuaj tiv thaiv tus nqi yog ncaj qha proportional rau thereactant concentration thiab cov units ntawm thawj qhov kev txiav txim tus nqi yog 1/sec.
Ib sab saum toj no, dab tsi yog units ntawm tus nqi tas li k rau qhov kev txiav txim thib ob? qhov twg k yog a thib ob xaj tus nqi tas li nrog units ntawm M -1 min-1 los yog M -1 s-1. Yog li, ob npaug ntawm qhov concentration ntawm reactant A yuav plaub npaug rau tus nqi ntawm tshuaj tiv thaiv.
Piv txwv li, cov units rau K yog dab tsi?
Cov units ntawm k nyob ntawm qhov kev txiav txim ntawm qhov tshwm sim, tab sis cov units yeej tsis yog Newtons ib 'meter'. Raws li piv txwv, rau thawj qhov kev txiav txim siab, k muaj cov units ntawm 1 / s thiab rau qhov kev txiav txim thib ob, units ntawm 1/M.s.
Tus nqi tas li k yog dab tsi?
Hauv tshuaj kinetics ib qho tshuaj tiv thaiv tus nqi tas li kev hais lus tus nqi coefficient, k , quantifies cov tus nqi ntawm ib qho tshuaj tiv thaiv. Rau cov tshuaj tiv thaiv ntawm reactants A thiab B los tsim cov khoom C a A + b B → c C. tus nqi feem ntau pom muaj daim ntawv: Ntawm no k (T) yog cov tshuaj tiv thaiv tus nqi tas li uas nyob ntawm qhov kub thiab txias.

Yuav ua li cas koj pom tus nqi ntawm cosine ntawm daim duab peb sab?
Hauv txhua daim duab peb sab, lub cosine ntawm lub kaum sab xis yog qhov ntev ntawm sab uas nyob ib sab (A) faib los ntawm qhov ntev ntawm lub hypotenuse (H). Nyob rau hauv ib tug qauv, nws yog sau yooj yim li 'cos'. Feem ntau nco ntsoov li 'CAH' - lub ntsiab lus Cosine yog nyob ib sab ntawm Hypotenuse
Yuav ua li cas koj hloov cov units me mus rau cov units loj?
Hloov cov chav me me mus rau cov chav loj loj dua chav tsev loj. Txhawm rau hloov los ntawm chav tsev loj dua mus rau ib qho me me, sib npaug. Txhawm rau hloov los ntawm chav tsev me mus rau qhov loj dua, faib
Yuav ua li cas koj thiaj nrhiav tau tus nqi ploj ntawm tus nqi tsim?
Tus nqi ntawm ib qho tshuaj tiv thaiv yog qhov kev hloov hauv kev concentration ntawm qhov kev hloov ntawm lub sijhawm. Cov tshuaj tiv thaiv tuaj yeem txhais tau li no: tus nqi ploj ntawm A tus nqi = −Δ [A] Δt. tus nqi ploj ntawm B tus nqi = − Δ [B] Δt. tus nqi tsim ntawm C tus nqi = Δ [C] Δt. tus nqi tsim ntawm D) tus nqi = Δ [D] Δt
Yuav ua li cas koj yuav soj ntsuam cov nyhuv ntawm lub teeb siv ntawm tus nqi ntawm photosynthesis?
Cov nyhuv ntawm lub teeb siv ntawm photosynthesis tuaj yeem tshawb xyuas hauv cov nroj tsuag dej. Qhov kev siv lub teeb yog proportional rau qhov kev ncua deb - nws yuav txo qis raws li qhov deb ntawm lub teeb nce - yog li lub teeb siv rau kev tshawb nrhiav tuaj yeem sib txawv los ntawm kev hloov qhov kev ncua deb ntawm lub teeb mus rau cov nroj tsuag
