Yog tias qhov tshuaj tiv thaiv ΔH yog qhov tsis zoo, thiab ΔS yog qhov zoo, cov tshuaj tiv thaiv ib txwm nyiam qhov ntsuas kub. Yog tias cov tshuaj tiv thaiv ΔH yog qhov zoo, thiab ΔS yog qhov tsis zoo, cov tshuaj tiv thaiv ib txwm yog qhov tsis txaus siab.

Dab tsi yog qhov nyiam tshaj qhov ntsuas kub?

Re: Nws txhais li cas rau cov tshuaj tiv thaiv "thermodynamically nyiam?" Cov tshuaj tiv thaiv uas tsis xav tau lub zog pom tias muaj txiaj ntsig zoo dua. Txij li cov tshuaj tiv thaiv exothermic tso tawm lub zog thiab cov tshuaj tiv thaiv endothermic xav tau lub zog, cov tshuaj tiv thaiv exothermic yog qhov zoo dua.

Dab tsi yog qhov kub thiab txias yog qhov nyiam tshaj plaws?

lej, ΔG yuav dhau los ua qhov zoo tsuas yog thaum T yog ntau dua 313K. Vim li no, cov tshuaj tiv thaiv yog qhov zoo tshaj plaws ntawm qhov kub thiab txias tsawg dua 313K (vim ΔG yuav tsis zoo), tab sis tsis yog thermodynamically haum rau qhov kub siab tshaj 313K (vim ΔG yuav zoo).

Dab tsi txiav txim siab qhov ntsuas kub zoo?

Thermodynamic stability nyob ntawm txawm los yog tsis qhov tshuaj tiv thaiv yog tus kheej. Qhov no nyob ntawm qhov hloov pauv ntawm lub zog dawb (ΔG). Cov tshuaj tiv thaiv thermodynamically ruaj khov yog ib qho uas tsis tshua muaj tshwm sim. Yog li ntawd, nws yog kev ywj pheej ntawm txoj kev ntawm reactants thiab cov khoom.

Raws li qhov twg ntawm cov xwm txheej hauv qab no yog cov tshuaj tiv thaiv thermodynamically nyiam?

Cov tshuaj tiv thaiv yog thermodynamicallyhaum tsuas yog ntawm kub siab tshaj 25 ° C. Ntawm 25 ° C, ∆G ° rau cov tshuaj tiv thaiv yog qhov zoo.
