Kev tshwm sim intermediates yog tsim nyob rau hauv ib tug kauj ruam thiab tom qab ntawd tau noj hauv ib qho tom qab kauj ruam ntawm tshuaj tiv thaiv mechanism . Cov qeeb tshaj kauj ruam hauv tshuab yog hu ua tus nqi txiav txim los yog tus nqi txwv kauj ruam . Zuag qhia tag nrho tshuaj tiv thaiv tus nqi yog txiav txim los ntawm tus nqi ntawm cov cov kauj ruam mus txog (thiab suav nrog) cov tus nqi-txhais kauj ruam.
Kuj kom paub yog, koj ua li cas thiaj nrhiav tau cov kauj ruam qeeb tshaj plaws hauv cov tshuaj tiv thaiv?
Tus nqi kev txiav txim kauj ruam yog cov qeeb tshaj kauj ruam ntawm ib qho tshuaj tshuaj tiv thaiv uas txiav txim siab qhov ceev (tus nqi) uas tag nrho tshuaj tiv thaiv ua tiav.
Teb
- Tus nqi txiav txim kauj ruam yog kauj ruam thib ob vim nws yog kauj ruam qeeb.
- 2NO + 2H2 → N2 + 2H2O.
- Cov intermediates hauv cov tshuaj tiv thaiv no yog N2O2 thiab N2O.
Tsis tas li ntawd, qhov kev txiav txim thawj zaug yog dab tsi? A ua ntej - xaj tshuaj tiv thaiv yog a tshuaj tiv thaiv uas ua tiav ntawm tus nqi uas nyob ntawm linearly ntawm tsuas yog ib qho reactant concentration.
Kuj tseem paub yog, vim li cas tus nqi txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws hauv cov tshuaj tiv thaiv txheej txheem?
Cov tus nqi - kev txiav txim siab kauj ruam yog kauj ruam qeeb tshaj plaws hauv cov txheej txheem tshuaj tiv thaiv . Vim nws yog tus qeeb tshaj plaws , nws txiav txim qhov tus nqi ntawm tag nrho tshuaj tiv thaiv . Qhov no yuav raug tshawb nrhiav tom qab hauv kev nthuav dav ntxiv. Hloov nyob rau hauv concentration ntawm cov tshuaj nyob rau lub sij hawm: Ib zajlus ntawm lub sij hawm piv rau concentration rau ob hom nyob rau hauv chemical equilibrium.
Koj pom qhov kev tshwm sim tag nrho li cas?
Cov tag nrho cov tshuaj tiv thaiv tus nqi yog txiav txim siab los ntawm tus nqi ntawm cov kauj ruam mus txog (thiab suav nrog) cov kauj ruam qis tshaj. Cov kauj ruam qeeb tshaj hauv a tshuaj tiv thaiv mechanism yog hu ua tus nqi txiav txim los yog tus nqi limiting kauj ruam. Rau peb qhov piv txwv mechanism nyob rau hauv seem dhau los, tus nqi txwv cov kauj ruam yog thawj theem pib.

Yuav ua li cas koj daws ob kauj ruam sib npaug hauv pre algebra?
VIDEO Ib yam li ntawd, 4 kauj ruam los daws qhov sib npaug yog dab tsi? A 4-Step Guide to Solving Equations (Part 2) Kauj Ruam 1: Simplify txhua sab ntawm qhov sib npaug. Raws li peb tau kawm dhau los, thawj kauj ruam ntawm kev daws qhov sib npaug yog ua kom qhov sib npaug yooj yim li sai tau.
Dab tsi yog cov kauj ruam los daws qhov tsis sib xws ntawm ob kauj ruam?
Nws yuav siv ob kauj ruam los daws qhov kev sib npaug lossis qhov tsis sib xws uas muaj ntau tshaj ib qho kev ua haujlwm: Simplify siv qhov sib txawv ntawm qhov sib ntxiv lossis rho tawm. Ua kom yooj yim ntxiv los ntawm kev siv qhov sib txawv ntawm qhov sib npaug lossis faib
Nyob rau theem twg DNA nyuaj tshaj plaws kom pom nyob rau hauv lub tshuab tsom iav?
DNA yog qhov nyuaj tshaj plaws kom pom ntawm prophase theem ntawm mitosis. Kev piav qhia: Nyob rau theem prophase, tsis muaj cov chromosomes txhais tau zoo. DNA yog tam sim no nyob rau hauv daim ntawv ntawm nyias chromatin fibers uas nyuaj rau pom nyob rau hauv lub microscope

Koj ua li cas electron configuration kauj ruam yog kauj ruam?
Cov kauj ruam Nrhiav koj tus lej atomic. Txiav txim siab tus nqi ntawm lub atom. Nco cov npe ntawm cov orbitals. Nkag siab txog kev teeb tsa hluav taws xob. Nco qhov kev txiav txim ntawm lub orbitals. Sau rau hauv lub orbitals raws li tus naj npawb ntawm electrons hauv koj lub atom. Siv lub sij hawm ntev raws li qhov pom kev luv luv
