Isingeniso kuI-Copper oxide nge-hydrogen

Ukusabela kwamakhemikhali phakathi kweCopper (II) i-Oxide (CUO) ne-Hydrogen Gas (H2) kuyisibonelo esibonisa ukusabela kweRedox kumakhemikhali, kuvame ukubhekelwa kuzo zombili izinjongo zokufundisa kanye nezicelo zezimboni. Le ndatshana idlulela kuhlobo lwalokhu kusabela, ihlole ukuthi ingabe i-expothermic noma i-endothermic, egxile kakhulu kwimigomo yesayensi ebabazekayo, idatha ebonakalayo, kanye nemithelela yayo ebanzi.

I-Chemical Equation nokubuka konke

Ukuphendula kungavezwa yi-equation yamakhemikhali:

• CUO (S) + H2 (g) → CU (s) + H2O (g)

Kulokhu kuncishiswa - Inqubo ye-oxidation (redox), ithusi), i-Copper (II) i-oxide incishiswa ithusi, futhi i-hydrogen ichazwa ngamanzi. Lokhu kuphendula kusebenza njengetshe eliyisisekelo elikhuphukayo kumakhemikhali, okubonisa imiqondo eyisisekelo yokudluliselwa kwe-elektroni kanye nezinguquko zamandla.

Ukuqonda ukuphendula okuxolelisayo kanye ne-endothermic

Ukusabela kwamakhemikhali kuhlukaniswe kabanzi kwizigaba ezi-epholothermic kanye ne-endothermic, ngokusekelwe ekuguqulweni kwamandla abo. Ukuqonda le miqondo kubalulekile ukuhlaziya i-Copper oxide nokusabela kwe-hydrogen.

Izinguquko zamandla nokugeleza kokushisa

Ukuphendula okuphakamisayo kukhipha amandla, imvamisa ngesimo sokushisa, endaweni ezungezile. Ngokuphambene nalokho, ukusabela okukhona e-endothermic kudonsa amandla emvelweni yawo. La mandla avame ukukalwa nge-kilojoules nge-mole (KJ / Mol), ukuhlinzeka ukuqonda ngokuqina kwe-thermodynamic kanye nokuziqhenya kokuphendula.

Ifomula yamakhemikhali kanye nendlela yokuphendula

Indlela yokuphendula yeCopper Oxide ne-hydrogen kubandakanya ukudluliswa kwama-elektroni nokuphuka nokwakhiwa kwamabhondi zamakhemikhali. Kubalulekile ukuhlola iphrofayili yamandla yokuphendula ukuze kunqunywe isimo sayo se-exothermic noma endothermic.

Ukucatshangelwa Kwe-Bond Energy

Ngokuhlaziya ukusabela, cabanga ngamandla wokuhlukaniswa ngebhondi kanye nokwakhiwa kwezibopho ezintsha. Amabhondi e-O - H asungulwe kumanzi akhipha amandla abalulekile, okuyisici esibalulekile ekunqumeni ukuguqulwa kwamandla okujwayelekile kokuphendula.

I-Thermodynamics: Izinguquko zamandla ekuphendukeni

I-Thermodynamics inikeza uhlaka oluningi lokuqonda izinguquko zamandla ezihambisana nokusabela kwamakhemikhali.

Ama-Gibbs Energy kanye ne-Spontaneity

I-Gibbs Free Energy Change (ΔG) yokuphendula ingabalwa kusetshenziswa ushintsho lwe-Entholpy Change (ΔH) kanye noshintsho lwe-Entropy (Δ) endaweni yokushisa enikeziwe:

• ΔG = H - Amathambeko

I-ΔG engemihle ikhombisa inqubo ezenzakalelayo, kanye ne-Copper oxide kanye nokusabela kwe-hydrogen, ΔG akunangqondo ezimweni ezijwayelekile, kuqinisekisa imvelo yayo yokuzenzakalelayo neyokuqala.

Ukubona kanye nobufakazi

Idatha yokuhlola ihlinzeka ngemininingwane ebalulekile kwiphrofayela yamandla ye-Copper oxide kanye ne-hydrogen reaction.

Izifundo zeCaloriMetric

Ukuhlola amakhalori ukukala ukushisa okukhishwe ngesikhathi sokusabela, ngokujwayelekile ohlelweni oluvaliwe ukuqinisekisa ukunemba. Ukuphakanyiswa kokushisa okubonakalayo kuqinisekisa imvelo ephakeme, enamanani ajwayelekile enkosincy azungeze - 80 KJ / Mol, ekhombisa ukukhishwa kwamandla okubalulekile.

Izicelo zezimboni kanye nemiphumela

Lokhu kusabela akugcini nje kuphela kumakhemikhali e-theoretical kodwa futhi kunezicelo ezisebenzayo zezimboni.

Izinqubo zeMetallurgical

Ukwehliswa kwe-Copper oxide usebenzisa i-hydrogen kuyinqubo ebalulekile eMetAllurgy, esetshenziselwa abakhiqizi kanye nabathengisi ukukhiqiza nge-Pepper Metal ngempumelelo. Uhlobo oluphakanyisikhali lwalezi zinsiza zokuphendula ngokulondolozwa kwamandla phakathi kwamakhulu -

Qhathanisa amandla okuphendula: idatha ye-Empirical

Idatha enamandla ivumela ukuqhathanisa okuqondile koshintsho lwamandla ngokusabela okuhlukile, ukuhlinzeka ngesithombe esicacile sesimo esiphezulu se-oxide ye-Copper oxide kanye ne-hydrogen reaction.

Ukuhlaziywa kwedatha

I-Thermodymic Tables ibala izinguquko ezijwayelekile ze-Entholpy zokuphendula okuhlukahlukene. Nge-Copper Oxide ne-hydrogen, i-standard Entholpy Change imbi ngokwengeziwe uma iqhathaniswa nokunye ukuphendula okuningi, kugcizelela ukusebenza kwayo okuphezulu kwamandla kanye nezinhlelo zokusebenza zezimboni.

Ukucatshangelwa Kwezokuphepha ekuphendukeni okuphezulu

Ngenkathi ukusabela okuphezulu, okufana naleso ye-Copper oxide ne-hydrogen, nikeza izinzuzo ngokonga amandla, nazo zidinga ukuphatha ngokucophelela.

Ukuphathwa Kwengozi

Ukukhishwa okusheshayo kwamandla kungafaka izingozi zokuphepha ezilungiselelweni zezimboni. Izindlela ezifanele, njengezindawo ezilawulwayo kanye nezinqubomgomo zokuphepha, zibalulekile ukuze zinciphise ubungozi obuhambisana nenkulu eminingi -

Imibono yemfundo: Izinhlobo zokufundisa zokufundisa

Othisha badlala indima ebalulekile ekunikezeni ulwazi ngezinhlobo ezahlukahlukene zokusabela kwamakhemikhali nezimpawu zabo.

Ukuhlanganiswa Kwekharikhulamumu

I-Copper oxide nokusabela kwe-hydrogen kuvame ukufakwa eqenjini le-stem ukukhombisa ukusetshenziswa okusebenzayo kokuphendula okuhlosiwe. Izinsizakusebenza zemfundo kanye nezivivinyo zisiza ukudiliza le miqondo yabafundi futhi kukhuthaze ukuqonda okujulile kwe-thermodynamics.

Isiphetho: Ukufingqa kanye nemibono yesikhathi esizayo

Ukusabela phakathi kweCopper Oxide ne-hydrogen kusibonelo senqubo ephakeme, ebonakaliswa ukukhishwa kwamandla nezinhlelo zokusebenza ezisebenzayo embonini nasemfundo. Ukuqonda i-Thermodynamics kanye ne-kinetics yokusabela okunjalo kubalulekile ekuthuthukiseni ubuchwepheshe obusha kanye nokwenza ngcono izinhlaka zemfundo. Njengoba izimboni nabaphakeli bayaqhubeka nokwenza ngcono lezi zinqubo, izithembiso zesikhathi esizayo zisebenza kanzima kakhulu nokusimama kokukhiqizwa kwamakhemikhali.
