Notes:
The reaction between formic acid and HOBr in strongly acid aqueous media was studied by absorption spectrophotometry at 298 K. Bromine, the monitored species, displays a transient behavior, gradually rising up to a maximum and then decaying with first-order kinetics. Reaction rates, expressed as R = -dCBr2/dt, depend on the concentrations of HCOOH (0.1-1.4M), HOBr (0.3-1.5 × 10-3 M), and H+ (0.1-1.0M). The mechanism with k1 =1.04 ± 0.20M-1· s-1, k3 = 20.2M-1, quantitatively accounts for all observations within experimental error.
