From: A surface-stabilized ozonide triggers bromide oxidation at the aqueous solution-vapour interface
Implications for ozone uptake under atmospheric conditions. Predicted uptake coefficient for bulk reaction only (blue lines) and uptake coefficient due to surface reaction only (brown lines) for deliquesced sea salt solution equilibrated at 80% relative humidity (4.0 M Cl−) and a chloride to bromide ratio of 50 (light blue and light brown lines) and 500 (dark blue and dark brown)), as a function of the diameter of a spherical brine droplet or aerosol particle. The brown lines overlap, because the surface coverage of the bromide ozonide complex, and thus also the surface reaction rate, does not depend on the bromide concentration in the aqueous phase within the relevant range. This plot emphasizes the predominance of a surface process, especially for smaller particle sizes
