Kinetics and Mechanism of the Substitution Reaction of the Aquapentacyanoferrate(II) Ion with 1-Benzoylethylpyridinium Chloride [Elektronische Daten] [Jasna Lovrić, Blaženka Foretić, Nicoletta Burger] The carbonyl group of compounds of the phenacyl- and benzoylethyl-pyridinium type is recognized as a potential σ donor ligand which can produce complexes with the aquapentacyanoferrate(II) ion. Its reactive form is the ionized one i.e. the enolate ion. A detailed spectrophotometric investigation has been made for the reaction of the aquapentacyanoferrate(II) ion with 1-benzoylethylpyridinium chloride. The equilibrium constant of the produced complex was derived using two literatury available additional types of processing the molar ratio method's experimental data which were not found to be applied to this type of complexes. The kinetics of this substitution reaction were studied in buffered solutions at pH = 8.0 and I = 0.05M. The obtained results are consistent with a dissociative mechanism. © 2004 Oldenbourg Wissenschaftsverlag GmbH Thermodynamics & statistical physics nationallicence Laboratory techniques, experiments nationallicence Physical chemistry nationallicence Lovrić Jasna aut Foretić Blaženka aut Burger Nicoletta aut Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/11/2004(2004-11-01), 1289-1296 0942-9352 218:11/2004<1289 2004 218 zpch https://doi.org/10.1524/zpch.218.11.1289.50813 text/html Onlinezugriff via DOI 1 research article jats NATIONALLICENCE 856 40 https://doi.org/10.1524/zpch.218.11.1289.50813 text/html Onlinezugriff via DOI NATIONALLICENCE 700 1- Lovrić Jasna aut NATIONALLICENCE 700 1- Foretić Blaženka aut NATIONALLICENCE 700 1- Burger Nicoletta aut NATIONALLICENCE 773 0- Zeitschrift für Physikalische Chemie/International journal of research in physical chemistry and chemical physics Oldenbourg Wissenschaftsverlag GmbH 218/11/2004(2004-11-01), 1289-1296 0942-9352 218:11/2004<1289 2004 218 zpch CC0 http://creativecommons.org/publicdomain/zero/1.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-gruyter
