Qhov sib txawv tseem ceeb ntawm photochemical thiab electrochemical cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv photochemical tshwm sim vim qhov nqus ntawm lub teeb lub zog, thaum cov tshuaj electrochemical tshwm sim vim qhov nqus ntawm hluav taws xob.
Cov tshuaj tiv thaiv kev yees duab thiab cov tshuaj tiv thaiv electrochemical yog ob hom tshuaj tiv thaiv uas tshwm sim nyob rau hauv muaj ob lub zog sib txawv. Txawm li cas los xij, ob qho kev cuam tshuam no feem ntau yog cov tshuaj tiv thaiv kab mob endothermic.
Photochemical Reaction yog dab tsi?
Cov tshuaj tiv thaiv photochemical yog ib hom tshuaj tiv thaiv uas tau pib los ntawm kev nqus ntawm lub zog hauv daim ntawv ntawm lub teeb. Thiab, qhov kev nqus ntawm lub zog ntawm cov molecules no ua rau kev tsim lub sijhawm zoo siab rau lub xeev uas nws cov tshuaj lom neeg thiab lub cev muaj zog txawv ntawm qhov qub qub ntawm cov molecule. Cov tshuaj uas tsim tawm tshiab txawv ntawm lub xeev thawj zaug los ntawm kev hloov mus rau cov qauv tshiab (ntawm kev sib txuas nrog ib leeg lossis lwm cov molecules, ntawm kev hloov hluav taws xob, hydrogen atoms, protons, thiab lwm yam.
Thaum muab piv rau lub xeev qub ntawm cov molecule, lub xeev zoo siab muaj lub zog acidic, thiab nws yog qhov muaj zog dua li qub lub xeev. Ntxiv mus, nyob rau hauv cov txheej txheem photochemical yooj yim tshaj plaws, cov xeev zoo siab yuav emit lub teeb nyob rau hauv daim ntawv ntawm fluorescence.
Daim duab 01: Photosynthesis
Cov txheej txheem photochemical feem ntau hauv ntiaj teb yog photosynthesis. Lub neej hauv ntiaj teb feem ntau yog nyob ntawm cov txheej txheem ntawm photosynthesis. Hauv cov txheej txheem no, cov nroj tsuag tuaj yeem hloov lub zog ntawm lub hnub ci mus rau hauv cov khoom siv hluav taws xob los ntawm kev tsim cov carbohydrates (siv cov pa roj carbon dioxide thiab dej los ntawm huab cua). Tsis tas li ntawd, cov txheej txheem no tso tawm cov pa oxygen mus rau qhov chaw. Txij li feem ntau ntawm lub hnub ci mus txog lub ntiaj teb huab cua, feem ntau cov txheej txheem uas tshwm sim hauv ntiaj teb yog cov tshuaj tiv thaiv photochemical.
Electrochemical Reaction yog dab tsi?
Ib qho tshuaj tiv thaiv hluav taws xob yog ib hom tshuaj tiv thaiv uas tau nrog los ntawm kev hla ntawm hluav taws xob tam sim no. Feem ntau, hom kev cuam tshuam no cuam tshuam nrog kev hloov ntawm electrons ntawm ob yam khoom (ib yam khoom yog ib qho khoom, thiab lwm yam khoom yog kua).
Daim duab 02: Hluav taws xob Cell
Feem ntau, qhov tshwm sim ntawm cov tshuaj tiv thaiv tshuaj tshwm sim los ntawm kev tso tawm lossis nqus cua sov (tsis yog lwm hom ntawm lub zog). Tab sis, muaj peev xwm muaj ntau lwm yam kev tshwm sim uas tshwm sim hauv kev sib cuag nrog hluav taws xob conductors, sib cais los ntawm kev ua cov xov hlau. Tsis tas li ntawd, cov txheej txheem no tso tawm hluav taws xob hluav taws xob uas muaj hluav taws xob tsim tawm. Thiab, lub zog hluav taws xob no tuaj yeem siv los ua tshuaj lom neeg los ntawm kev siv lub zog ua lub zog.
Cov kab ke ntau tshaj peb paub tias siv hluav taws xob los coj cov tshuaj lom neeg yog lub xov tooj hluav taws xob. Ntawm no, electrolysis ua rau kev hloov pauv ntawm ib qho tshuaj mus rau hauv ib yam khoom sib txawv los ntawm kev sib koom ua ke thiab kev sib koom ua ke.
Qhov txawv ntawm Photochemical thiab Electrochemical Reaction yog dab tsi?
Photochemical thiab electrochemical cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv uas tshwm sim los ntawm ob lub zog sib txawv. Qhov sib txawv tseem ceeb ntawm photochemical thiab electrochemical cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv photochemical tshwm sim vim qhov nqus ntawm lub teeb lub zog, thaum cov tshuaj tiv thaiv electrochemical tshwm sim vim qhov nqus ntawm hluav taws xob.
Cov kab lus hauv qab no nthuav tawm cov ntsiab lus ntxiv ntawm qhov sib txawv ntawm photochemical thiab electrochemical tshuaj tiv thaiv.
Summary – Photochemical vs Electrochemical Reaction
Photochemical thiab electrochemical cov tshuaj tiv thaiv yog tshuaj lom neeg cov tshuaj tiv thaiv uas tshwm sim nyob rau hauv muaj ob lub zog sib txawv. Qhov sib txawv tseem ceeb ntawm photochemical thiab electrochemical cov tshuaj tiv thaiv yog tias cov tshuaj tiv thaiv photochemical tshwm sim vim qhov nqus ntawm lub teeb lub zog, thaum cov tshuaj electrochemical tshwm sim vim qhov nqus ntawm hluav taws xob.
