Qhov Tseem Ceeb Qhov txawv - Unimolecular vs Bimolecular Reactions

Nyob hauv chemistry, lo lus molecularity yog siv los qhia cov naj npawb ntawm cov molecules uas tuaj ua ke los ua rau hauv cov tshuaj tiv thaiv theem pib. Cov tshuaj tiv thaiv theem pib yog ib kauj ruam cov tshuaj tiv thaiv uas muab cov khoom kawg ncaj qha tom qab cov tshuaj tiv thaiv ntawm cov reactants. Qhov no txhais tau hais tias cov tshuaj tiv thaiv theem pib yog cov tshuaj tiv thaiv uas tsis muaj cov kauj ruam nruab nrab ua ntej tsim cov khoom kawg. Cov tshuaj tiv thaiv bimolecular thiab bimolecular yog cov tshuaj tiv thaiv theem pib. Qhov sib txawv tseem ceeb ntawm Unimolecular thiab bimolecular cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv unimolecular koom nrog tsuas yog ib qho molecule ua ib qho reactant thaum cov tshuaj tiv thaiv bimolecular koom nrog ob lub molecules ua reactants.

Yuav Ua Li Cas Thiaj Tsis Pom Zoo?

Cov tshuaj tiv thaiv tsis muaj tshuaj tiv thaiv yog cov tshuaj tiv thaiv theem pib uas tsuas muaj ib qho molecule ua ib qho reactant. Nyob ntawd, cov tshuaj tiv thaiv yog ib qho kev hloov kho tshiab. Ib qho molecule rearranges los tsim ntau cov molecules sib txawv raws li cov khoom kawg. Tab sis qhov no tshwm sim hauv ib kauj ruam. Tsis muaj cov kauj ruam nruab nrab uas cov reactant molecule undergoes hauv kev tsim cov khoom kawg. Nws ncaj qha muab cov khoom kawg. Qhov sib npaug rau cov tshuaj tiv thaiv tuaj yeem muab tau raws li

A → P

Ntawm A yog reactant thiab P yog cov khoom. Raws li thawj qhov kev txiav txim ntawm tus nqi txoj cai, tus nqi ntawm cov tshuaj tiv thaiv tuaj yeem muab raws li hauv qab no.

Rate=k [reactant]

Qee yam piv txwv ntawm cov tshuaj tiv thaiv tsis zoo muaj xws li hauv qab no:

Daim duab 01: Cyclopropane rearrangement rau daim ntawv propane.

1. Conversion of N₂O₄ mus ua ob NO_{2 molecules}
2. Kev hloov pauv ntawm cyclopropane rau propene
3. Conversion of PCl₅ into PCl₃ and Cl₂

Dab tsi yog qhov cuam tshuam bimolecular?

Cov tshuaj tiv thaiv bimolecular yog cov tshuaj tiv thaiv theem pib uas muaj ob lub molecules ua reactants. Nws tuaj yeem piav raws li kev sib tsoo ntawm ob lub molecules los yog hais. Cov no yog cov tshuaj tiv thaiv kab mob hauv cov organic thiab inorganic chemistry. Ob lub molecules tuaj yeem yog tib yam lossis ntau hom. Piv txwv li, ob lub molecules tuaj yeem yog ob lub NOCl molecules nrog tib lub atomic kev npaj lossis tuaj yeem yog C thiab O _{2 muaj qhov sib txawv ntawm atomic. Qhov sib npaug rau cov tshuaj tiv thaiv bimolecular yog muab raws li hauv qab no.}

A + A → P

A + B → P

Daim duab 02: Daim duab hluav taws xob rau cov tshuaj tiv thaiv bimolecular.

Vim tias muaj ob lub reactants, cov tshuaj tiv thaiv no tau piav qhia raws li qhov kev txiav txim thib ob. Yog li ntawd, cov tshuaj tiv thaiv bimolecular no tau piav qhia los ntawm txoj cai lij choj thib ob;

Rate=[A]²

Or

Rate=[A][B]

Nyob hauv qhov kev txiav txim tag nrho yog ib txwm 2. Qee qhov piv txwv ntawm cov tshuaj tiv thaiv bimolecular tau muab hauv qab no.

1. Reaction between CO and NO₃
2. Reaction ntawm ob NOCl molecules
3. Reaction ntawm Cl thiab CH ₄

Dab tsi yog qhov zoo sib xws ntawm Unimolecular thiab bimolecular Reactions?

• Ob qho tib si Unimolecular thiab bimolecular Reactions yog cov tshuaj tiv thaiv theem pib.
• Ob leeg Unimolecular thiab bimolecular cov tshuaj tiv thaiv muab cov khoom lag luam hauv ib kauj ruam.
• Ob qho tib si Unimolecular thiab bimolecular cov tshuaj tiv thaiv tsis muaj cov kauj ruam nruab nrab.
