Ntawm cov ntsiab lus muab, the NH3 yog qhov yooj yim tshaj plaws. Li no muaj ntau tshaj plaws proton affinity.
Qhov kev sib raug zoo ntawm proton txhais li cas?
Qhov siab dua cov proton affinity, lub hauv paus muaj zog dua thiab qhov tsis muaj zog ntawm cov kua qaub nyob hauv theem roj . … Lub hauv paus paub tsis muaj zog tshaj plaws yog helium atom (Epa=177.8 kJ/mol), ua rau cov hydrohelium (1+) ion lub zog paub proton acid.
proton affinity yog dab tsi?
Proton affinity ntawm A− yog txhais tias qhov tsis zoo ntawm qhov hloov pauv enthalpy (ΔH) ntawm cov txheej txheem hauv Eq. 1 , thiab cov roj-theem theem pib ntawm A- yog txhais tias yog qhov tsis zoo ntawm Gibbs tsis muaj zog hloov pauv (ΔG). … Tus qauv lub xeev nyob rau hauv cov roj-theem yog rau ib tug mole ntawm hais ntawm 298.15 K thiab 1 atm siab.
Koj pom qhov kev sib raug zoo ntawm proton li cas?
Proton affinity is computed as PA=E(Ac-) + E(H+) - E(HAc), ua rau qhov kawg proton affinity ntawm 0.5704 Hartree, los yog 357.93 kcal / mol. Peb tso nws ua piv txwv los xam cov PA nrog DFTB2 (SCC-DFTB), thiab muab piv nrog cov qhab nia qib siab ab initio uas kuj tau hais hauv daim ntawv DFTB3.
Yuav ua li cas ntawm cov hydrides hauv qab no muaj ntau tshaj plaws proton affinity?
Vim li no, qhov siab tshaj plaws proton affinity yuav pom los ntawm ammononia, kev xaiv D.
