英文摘要	Nitrogen oxides are removed from the troposphere through the reactive uptake of N2O5 into aqueous aerosol. This process is thought to occur within the bulk of an aerosol, through solvation and subsequent hydrolysis. However, this perspective is difficult to reconcile with field measurements and cannot be verified directly because of the fast reaction kinetics of N2O5. Here, we use molecular simulations, including reactive potentials and importance sampling, to study the uptake of N2O5 into an aqueous aerosol. Rather than being mediated by the bulk, uptake is dominated by interfacial processes due to facile hydrolysis at the liquid-vapor interface and competitive reevaporation. With this molecular information, we propose an alternative interfacial reactive uptake model consistent with existing experimental observations. © 2021 American Association for the Advancement of Science.
