Siab, kub, concentration thiab muaj cov catalysts tuaj yeem cuam tshuam tus nqi ntawm cov tshuaj tiv thaiv

  1. Siab ntawm Gases. Rau cov tshuaj tiv thaiv nrog gases, siab muaj zog cuam tshuam rau tshuaj tiv thaiv tus nqi.
  2. Concentration of Solutions.
  3. Kub thiab txias.
  4. Exposed Surface Area.
  5. Catalysts thiab Activation Zog.
  6. Sensitivity rau lub teeb.

Kuj kom paub yog, plaub txoj hauv kev ua kom cov tshuaj tiv thaiv kab mob yog dab tsi?

Ua kom qhov kub thiab txias hauv Endothermic cov tshuaj tiv thaiv ( Cov tshuaj tiv thaiv uas nqus zog, los yog txias) Txo qhov kub thiab txias hauv Exothermic cov tshuaj tiv thaiv ( Cov tshuaj tiv thaiv uas tso tawm lub zog, los yog kub) Ntxiv ib qho catalyst (Ib yam khoom uas txo lub zog ua kom muaj zog, ua kom ceev tus tshuaj tiv thaiv ) Ua kom cov concentration ntawm reactants.

Qhov thib ob, dab tsi tuaj yeem ua kom muaj kev cuam tshuam? Muaj ntau ntau yam uas cuam tshuam rau qhov ceev ntawm cov tshuaj tiv thaiv:

  • Qhov xwm ntawm cov reactants.
  • Particle loj ntawm cov reactants.
  • Concentration ntawm cov reactants.
  • Siab ntawm gaseous reactants.
  • Kub.
  • Catalysts.

Cov lus nug tseem yog, dab tsi yog 5 txoj hauv kev txhawm rau txhawm rau txhawm rau tshuaj lom neeg?

Cov ntsiab lus hauv cov teeb no (5)

  • kub. nce kub = ntau kev sib tsoo.
  • thaj chaw saum npoo. nce nto yog = ntau kev sib tsoo.
  • concentration. siab concentration = ntau sib tsoo.
  • catalysts. txo qis lub zog xav tau rau cov tshuaj tiv thaiv.
  • yam ntawm reactants. qee yam tshuaj muaj zog ntau dua li lwm tus.

Dab tsi tuaj yeem ua kom ceev cov tshuaj tiv thaiv?

Muaj plaub yam tseem ceeb uas tuaj yeem cuam tshuam cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv tshuaj:

  • Reactant concentration. Ua kom cov concentration ntawm ib los yog ntau tshaj reactants feem ntau yuav ua rau tus nqi ntawm cov tshuaj tiv thaiv.
  • Lub cev lub cev ntawm cov reactants thiab thaj chaw saum npoo.
  • Kub.
  • Kev muaj tus catalyst.
