Ib daim duab zog tuaj yeem txhais tau tias yog a daim duab qhia cov txheeb ze muaj peev xwm ntawm cov reactants, hloov pauv lub xeev, thiab cov khoom raws li cov tshuaj tiv thaiv zoo zuj zus nrog lub sijhawm.
Raws li txoj cai, daim duab hluav taws xob qhia dab tsi?
Cov zog Kev hloov pauv uas tshwm sim thaum muaj tshuaj lom neeg ua tau qhia hauv a daim duab hu ua lub peev xwm daim duab zog , los yog qee zaum hu ua kev hloov pauv hloov pauv. Ib lub peev xwm lub zog daim duab qhia qhov kev hloov ntawm lub peev xwm zog ntawm ib tug system li reactants yog hloov mus rau hauv cov khoom.
Kuj Paub, daim duab qhia lub zog pub dawb yog dab tsi? Cov Gibbs dawb zog graph qhia tau hais tias los yog tsis muaj cov tshuaj tiv thaiv yog tshwm sim - txawm tias nws yog exergonic los yog endergonic. ΔG yog qhov hloov pauv hauv dawb zog . Feem ntau, txhua qhov kev xav xav mus rau qis dua zog lub xeev, yog li qhov kev hloov tsis zoo yog nyiam.
Tsis tas li ntawd, koj ua li cas kos ib daim duab kos duab?
1 Teb
- Kos thiab sau ib khub ntawm axes. Sau lub axis ntsug "Lub Zog Muaj Peev Xwm" thiab kab rov tav axis "Reaction Coordinate".
- Kos thiab sau ob kab kab rov tav luv los cim lub zog ntawm cov reactants thiab cov khoom.
- Kos daim duab qhia qib zog.
- Kos thiab sau lub zog ua kom muaj zog.
Koj txhais li cas enthalpy?
Enthalpy yog ib qho khoom siv thermodynamic ntawm ib qho system. Nws yog tus lej ntawm lub zog sab hauv ntxiv rau cov khoom ntawm lub siab thiab ntim ntawm lub cev. Nws qhia txog lub peev xwm ua haujlwm tsis yog siv tshuab thiab lub peev xwm tso tawm cua sov. Enthalpy yog denoted li H; tshwj xeeb enthalpy npe h.

Lub ntsiab txhais ntawm lo lus hluav taws xob hluav taws xob yog dab tsi?
Npe. Cov hluav taws xob hluav taws xob txhais tau tias yog hluav taws xob hluav taws xob uas tso cai rau kev ua haujlwm kom tiav. Ib qho piv txwv ntawm lub zog hluav taws xob yog lub zog los ntawm lub qhov hluav taws xob ntsaws. YourDictionary txhais thiab siv piv txwv
Vim li cas cov hluav taws xob sab nraud tsuas yog suav nrog hauv daim duab kos duab hluav taws xob?
Atoms nrog 5 los yog ntau tshaj valence electrons tau electrons tsim ib tug tsis zoo ion, los yog anion. Vim li cas thiaj li cov hluav taws xob sab nraud tsuas yog cov uas suav nrog hauv daim duab orbital filling? lawv tsuas yog cov uas koom nrog cov tshuaj tiv thaiv thiab kev sib raug zoo. 2s orbital nyob deb ntawm lub nucleus txhais tau tias nws muaj zog ntau dua
Dab tsi yog qhov txawv ntawm kev txuag hluav taws xob thiab lub hauv paus ntsiab lus ntawm kev txuag hluav taws xob?
Lub caloric txoj kev xav tau khaws cia tias cov cua sov tsis tuaj yeem tsim los yog rhuav tshem, qhov kev txuag ntawm lub zog ua rau lub hauv paus ntsiab lus tsis sib xws uas cov cua sov thiab cov tshuab ua haujlwm sib hloov tau
Dab tsi yog cov yam ntxwv ua siab hloov hluav taws xob hloov hluav taws xob LET muaj thaum piv nrog LET hluav taws xob tsawg?
Dab tsi yog cov yam ntxwv ua kom muaj hluav taws xob hloov hluav taws xob siab (LET) hluav taws xob muaj thaum piv nrog cov hluav taws xob qis-LET? Cov huab hwm coj ntau ntxiv, txo qhov nkag mus. (Vim lawv cov nqi hluav taws xob thiab cov khoom loj heev, lawv ua rau ntau ionizations hauv cov ntaub so ntswg, sai sai poob lub zog
Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms?
Tus nqi zoo attracts tus nqi tsis zoo thiab ua rau lwm tus nqi zoo. Puas yog hluav taws xob them nqi hluav taws xob tsuas yog hluav taws xob lossis yog tus nqi ntawm tag nrho cov atoms? Cov nqi hluav taws xob yog cov cuab yeej ntawm tag nrho cov atoms
