Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab cov tshuaj tiv thaiv dissociation yog cov tshuaj tiv thaiv synthesis koom nrog kev tsim cov tshuaj tshiab los ntawm kev sib xyaw ntawm ob lossis ntau dua reactants whereas dissociation cov tshuaj tiv thaiv cuam tshuam nrog kev tawg ntawm ib qho kev sib xyaw ua ob lossis ntau yam khoom.
Cov tshuaj tiv thaiv kev sib xyaw thiab kev sib cais yog qhov sib txawv ntawm ib leeg. Cov tshuaj tiv thaiv synthesis piav qhia txog kev tsim cov khoom sib xyaw tshiab thaum cov tshuaj tiv thaiv dissociation piav qhia txog kev tawg ntawm ib qho chaw rau hauv nws cov khoom.
Dab tsi yog Kev Sib Tham Sib Tham?
A synthesis reaction is a type of chemical reaction in which two or more components together with each other to make a large compound. Nws yog qhov opposite ntawm dissociation cov tshuaj tiv thaiv. Nws kuj tseem hu ua kev sib xyaw ua ke ncaj qha thiab vim tias nws koom nrog kev sib xyaw ua ke los ua ib qho kev sib xyaw tshiab. Hauv cov tshuaj tiv thaiv no, cov reactants tuaj yeem yog cov tshuaj lom neeg lossis cov molecules. Cov khoom yog ib txwm ib tug compound los yog ib tug complex. Cov qauv dav dav rau qee cov tshuaj tiv thaiv yog raws li hauv qab no:
Qee yam piv txwv rau kev sib xyaw ua ke suav nrog kev sib xyaw ntawm cov pa roj carbon monoxide thiab cov pa oxygen los tsim cov dej molecules, kev sib xyaw ntawm carbon monoxide thiab oxygen los tsim cov pa roj carbon dioxide, kev sib xyaw ntawm txhuas hlau thiab cov pa roj carbon monoxide los ua txhuas oxide, thiab lwm yam..
Lub ntsiab lus tseem ceeb kom paub txog cov tshuaj tiv thaiv synthesis yog tias cov tshuaj tiv thaiv no muaj qhov sib xyaw ua ke ua cov khoom kawg hauv daim ntawv reactants. Nyob ntawd, tag nrho cov atoms tam sim no nyob rau hauv cov reactant molecules yuav tsum muaj nyob rau hauv cov khoom kawg yog hais tias nws yog ib tug synthesis tshuaj. Ntxiv mus, thaum tsim daim ntawv cog lus, cov tshuaj tiv thaiv no tso tawm lub zog; yog li ntawd, lawv yog exothermic tshua.
Dab tsi yog kev sib cais?
Cov tshuaj tiv thaiv Dissociation yog ib hom tshuaj tiv thaiv uas ib qho loj sib xyaw ua rau nws cov khoom. Nws yog qhov opposite ntawm ib tug synthesis tshuaj. Nyob rau hauv cov kev tshwm sim no, cov reactant feem ntau dhau ionization (lov rau hauv cov ionic Cheebtsam uas cov reactant yog ua los ntawm). Yog li ntawd, cov tshuaj tiv thaiv dissociation tuaj yeem raug hu ua cov tshuaj tiv thaiv ionization. Piv txwv li, dissociation ntawm ib tug dej molecule tsim hydroxide ion thiab hydrogen ion, ionization ntawm hydrochloric acid ua hydrogen ion thiab chloride anion.
Feem ntau cov kev cuam tshuam cuam tshuam tshwm sim hauv cov tshuaj aqueous lossis dej uas cov compound dissolves los ntawm ionization. Nws tshwm sim vim hais tias qhov zoo thiab tsis zoo ions ntawm lub compound yog attracted los ntawm qhov zoo thiab tsis zoo ncej ntawm ib tug dej molecule (polarity ntawm dej). Ntxiv mus, cov tshuaj tiv thaiv no xav tau lub zog rau cov txheej txheem kev sib cog lus; Yog li, lawv yog cov tshuaj tiv thaiv endothermic.
Qhov txawv ntawm Synthesis Reaction thiab Dissociation Reaction yog dab tsi?
Cov tshuaj tiv thaiv kev sib cais yog qhov sib txawv ntawm cov tshuaj tiv thaiv synthesis. Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab dissociation cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv synthesis cuam tshuam nrog kev tsim cov tshuaj tshiab los ntawm kev sib xyaw ntawm ob lossis ntau dua reactants whereas dissociation cov tshuaj tiv thaiv cuam tshuam nrog kev tawg ntawm ib qho kev sib xyaw rau hauv ob lossis ntau dua. Feem ntau, kev sib xyaw ua ke yog cov tshuaj tiv thaiv exothermic vim tias daim ntawv cog lus tso tawm lub zog thaum cov tshuaj tiv thaiv kev sib cais yog cov tshuaj tiv thaiv endothermic vim tias cov tshuaj tiv thaiv no xav tau lub zog rau kev sib tsoo. Ntxiv mus, cov khoom kawg ntawm cov tshuaj tiv thaiv synthesis yog ib qho chaw loj lossis ib qho nyuaj tab sis nyob rau hauv kev sib cuam tshuam, peb tuaj yeem soj ntsuam ob lossis ntau dua ionic Cheebtsam ua cov khoom.
Hauv qab infographic qhia txog qhov sib txawv ntawm cov tshuaj tiv thaiv synthesis thiab cov tshuaj tiv thaiv dissociation.
Summary – Synthesis Reaction vs Dissociation Reaction
Cov tshuaj tiv thaiv kev sib cais yog qhov sib txawv ntawm cov tshuaj tiv thaiv synthesis. Qhov sib txawv tseem ceeb ntawm cov tshuaj tiv thaiv synthesis thiab dissociation cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv synthesis cuam tshuam nrog kev tsim cov tshuaj tshiab los ntawm kev sib xyaw ntawm ob lossis ntau dua reactants whereas dissociation cov tshuaj tiv thaiv cuam tshuam nrog kev sib cais ntawm ib qho kev sib xyaw rau hauv ob lossis ntau dua.
