Reaction kinetic and equilibrium studies of the oxidation of oxalic acid by thallium(III) in aqueous perchlorate solutions
Abstract
The oxidation of oxalic acid by thallium(III) in 3 M (Na++ H+) perchlorate solutions can be described by the following scheme : Tl3++ H2C2O4⇌ TlC2O+4+ 2H+(K25°= 8.6 × 102 mol l.–1, ΔHo=–3.4 kcal mol–1) followed by TlC2O+4→ Tl++2 CO2(k= 1016.2 exp (–28.400/RT) s–1).
