Reaction: H· + Br₂ ® Br₂·^- + H⁺
Solvent: H₂O

k ~ 1 × 10¹⁰(L mol^-1 s^-1), pH = 1

Experimental method: Pulse radiolysis
Analytical method: vis-UV absorption
Data type: Absolute value measured directly

Product buildup kinetics at 360 nm (Br₂^-), competes favorably with H + O₂; uncertainty in the value is 5-fold.
