Study of the uptake of N2O5 by water and NaCl solutions

The uptake of N2O5 by pure water and NaCl solution was studied as a function of temperature in the range from 262 to 278 K with the droplet train technique, where a highly controlled beam of droplets was exposed to N2O5 in a low-pressure flow tube reactor, and the formation of nitrate in the liquid phase was determined by ion chromatography. The uptake coefficients, gamma, for N2O5 on pure water are observed to decrease from 0.03 to 0.013 with increasing temperature. (Abstract truncated)
