Abstract
The oxidation of iodide ion by chlorine dioxide has been studied by stopped-flow techniques at I = 1.0 M (NaClO 4 ). The following two-term rate law was confirmed for the reaction: −d[ClO 2 ]/dt = k I [ClO 2 ][I - ] + k II [ClO 2 ][I - ] 2 . The rate constants at 298 K and the activation parameters are k I = (1.87 ± 0.02) × 10 3 M - 1 s - 1 , ΔH I ⧧ = 35.4 ± 0.7 kJ/mol, ΔS I ⧧ = −63.5 ± 2.3 J/(mol K), k II = (1.25 ± 0.04) × 10 4 M - 2 s - 1 , ΔH I I ⧧ = 36.7 ± 1.3 kJ/mol, ΔS I I ⧧ = −43.2 ± 4.6 ...
