Kinetics and mechanisms of the CO2 and SO2 uptake by coordinate ion, cis-[Cr(C2O4)(L–L)(OH2)2]+ {(L–L) = methyl 3-amino-2,3-dideoxy-α-d-arabino-hexopyranoside} as studied by stopped-flow spectrophotometry

The kinetics of CO2 and SO2 uptake by a coordinate ion, cis-[Cr(C2O4)(L–L)(OH2)2]+, where L–L stands for a bidentate sugar ligand, methyl 3-amino-2,3-dideoxy-α-d-arabino-hexopyranoside has been studied, over temperature ranges of 5 – 25 and 5 – 20 °C for CO2 and SO2, respectively. Investigations were carried out using stopped-flow spectrophotometry in the range of 340–700 nm. Results of the kinetic measurements obtained for both gases were compared. The kinetics and mechanisms of the reactions were suggested and ΔH‡ values for both processes were determined.
