The reactions under study were investigated in aqueous solution in the 288\u2013308 K temperature range. In the case of the reaction between CO2 and cis-[Cr(C2O4)(BaraNH2)(OH2)2]+ cation variable pH values (6.82\u20138.91) and the constant ionic strength of solution (H+, Na+, ClO4\u2212 = 1.0) were used. Carbon dioxide was generated by the reaction between sodium pyruvate and hydrogen peroxide. The acid hydrolysis of cis-[Cr(C2O4)(BaraNH2)OCO2]\u2212 was investigated for varying concentrations of H+ ions (0.01\u20132.7 M). The obtained results enabled the determination of the number of steps of the studied reactions. Based on the kinetic equations, rate constants were determined for each step. Finally, mechanisms for both reactions were proposed and discussed. Based on the obtained results it was concluded that the carboxylation (CO2 uptake) reactions of cis-[Cr(C2O4)(BaraNH2)(OH2)2]+ and the decarboxylation (acid hydrolysis) of the cis-[Cr(C2O4)(BaraNH2)OCO2]\u2212 are the opposite of each other.<\/jats:p>","DOI":"10.3390\/molecules16097746","type":"journal-article","created":{"date-parts":[[2011,9,22]],"date-time":"2011-09-22T09:30:17Z","timestamp":1316683817000},"page":"7746-7761","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Stopped-Flow Spectrophotometric Study of the Kinetics and Mechanism of CO2 Uptake by cis-[Cr(C2O4)(BaraNH2)(OH2)2]+ Cation and the Acid-Catalyzed Decomposition of cis-[Cr(C2O4)(BaraNH2)OCO2]\u2212 Anion in Aqueous Solution"],"prefix":"10.3390","volume":"16","author":[{"given":"Dagmara","family":"Jacewicz","sequence":"first","affiliation":[{"name":"Department of General and Inorganic Chemistry, University of Gda\u0144sk, Sobieskiego 18\/19, 80-952 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandra","family":"D\u0105browska","sequence":"additional","affiliation":[{"name":"Department of General and Inorganic Chemistry, University of Gda\u0144sk, Sobieskiego 18\/19, 80-952 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lech","family":"Chmurzy\u0144ski","sequence":"additional","affiliation":[{"name":"Department of General and Inorganic Chemistry, University of Gda\u0144sk, Sobieskiego 18\/19, 80-952 Gda\u0144sk, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2011,9,9]]},"reference":[{"key":"ref_1","first-page":"147","article-title":"Carbonato complexes of cobalt(III)","volume":"2","author":"Maccoll","year":"1969","journal-title":"Coord.
