Reactive uptake
WebSep 1, 2024 · In Liu et al. (2015), gas-phase reactions leading to particulate NOC were assumed to be negligible based on (1) the observed anti-correlation between the calculated reactive uptake coefficient and NH 3 concentration, and (2) the exceedingly slow rate of the termolecular reaction between NH 3, acid, and carbonyls required in the gas phase to … WebThe reactive uptake coefficient of N 2 O 5 on liquid glycerol was also found to be relatively large with a value of (3.2–8.5) × 10 −4, suggesting that N 2 O 5 heterogeneous reactions with alcohols may also be atmospherically relevant. For all measurements with OA, CLA, and DES, the reactive uptake coefficients decreased significantly upon ...
