Iyini i-standard Gibbs free energy
Context:I-standard Gibbs free energy of formation (Gf°) yenhlanganisela ingukuguquka kwe-Gibbs free energy okuhambisana nokwakheka kwe-mole eyodwa yento esesimweni sayo esijwayelekile kusuka ezakhiweni zayo ezisezimweni zazo ezijwayelekile (ifomu elizinzile kakhulu lesakhi ku-1 bar yengcindezi kanye nokushisa okucacisiwe, imvamisa i-298.15 K noma i-25 ° C).  Ithebula elingezansi libonisa umsebenzi ojwayelekile kaGibbs wokwakheka kwezakhi eziningana kanye nezinhlanganisela zamakhemikhali futhi uthathwe kuLange's Handbook of Chemistry. Qaphela ukuthi wonke amanani abhalwe ngo-kJ/mol. Amathebula anemininingwane eminingi kakhulu angatholakala encwadini ethi CRC Handbook of Chemistry and Physics nasematafuleni e-NIST JANAF. I-NIST Chemistry WebBook (bheka isixhumanisi esingezansi) iyinsiza eku-inthanethi equkethe i-enthalpy ejwayelekile yokwakheka kwama-compound ahlukahlukene kanye ne-entropy ejwayelekile ngokuphelele yalezi zinhlanganisela lapho kungalinganiswa khona amandla we-Gibbs wamahhala wokwakheka.
