Tag nrho tshuaj tiv thaiv , txawm exothermic cov tshuaj tiv thaiv , xav tau activation zog pib. Activation zog yog xav tau coj reactants ua ke kom lawv ua tau teb . Ceev npaum li cas a tshuaj tiv thaiv tshwm sim yog hu ua tshuaj tiv thaiv tus nqi.
Yog li ntawd, dab tsi yog lub zog xav tau los pib cov tshuaj tiv thaiv?
Cov lub zog xav tau los pib tshuaj tiv thaiv hu ua activation zog . Ua kom zog zoo li lub laub me nyuam xav tau pib mus rau ib qho chaw ua si swb.
Ib tug kuj yuav nug, vim li cas lub zog yuav tsum tau pib ua tshuaj tiv thaiv? Endothermic tshuaj tiv thaiv ua kom zog yog xav tau rau kev sib tsoo muaj zog xav tau txiav cov kev sib txuas ntawm cov atoms. Yuav kom tau txais kev sib tsoo muaj zog dua peb xav tau atoms kom txav nrawm dua yog li muaj kinetic siab dua zog , yog li nce kub.
Ua raws li qhov kev pom no, dab tsi yuav tsum tau ua kom muaj tshuaj lom neeg tshwm sim?
Txhawm rau kom muaj tshuaj lom neeg tshwm sim, cov reactants yuav tsum sib tsoo. Kev sib tsoo ntawm cov molecules hauv cov tshuaj tiv thaiv tshuaj muab cov kinetic zog xav tau los rhuav tshem cov ntawv cog lus tsim nyog kom cov ntawv cog lus tshiab tuaj yeem tsim tau.
Puas yog txhua yam tshuaj tiv thaiv xav tau lub zog?
Tag nrho cov tshuaj tiv thaiv , suav nrog exothermic cov tshuaj tiv thaiv , xav tau ua kom zog pib. Ua kom zog yog xav tau yog li cov reactants tuaj yeem txav mus ua ke, kov yeej lub zog ntawm kev tawm tsam, thiab pib tawg cov ntawv cog lus.
