where is the accommodation coef cient, and i is the effective rate coef cient in the bulk or surface of the aerosol droplet. The result of this competition between reaction and transport is that many of the heterogeneous reactions of stratospheric importance are highly temperature dependent (through the temperature dependence of reactant solubilities and diffusivities) [27]. Reaction (7.23), for example, requires this kind of sophisticated kinetic treatment to capture its behaviour with temperature. At the other extreme from the liquid-reaction-controlled kinetics of reaction (7.25), reaction (7.22) occurs very ef ciently on aqueous surfaces, so that is a constant near unity. (The accepted value is 0.1.) For solid aerosol particles such as are found in some polar stratospheric clouds reactions in the bulk of the condensed phase do not occur. The physical chemistry of the reactions on the surfaces of solid particles depends on the details of the particle surface surface roughness, mobility on the surface, the existence of a quasi-liquid surface layer, etc. which are not well determined. It has yet to be established, for example, whether the surface of solid polar stratospheric cloud (PSC) particles is indeed solid, or if it consists of a quasi-liquid layer a few molecular radii deep (e.g. [28 30]). Studies of nely divided aqueous systems, which are stabilised nanometre-scale droplet populations, support the quasi-liquid layer hypothesis [31], at least for concentrated surface solutions of HCl. Without a robust theoretical model of solid PSC particle surfaces, calculated chlorine activation rates, and hence ozone depletion rates, remain very uncertain when the chlorine activation is occurring on solid PSCs.
