Figure S3. Linear relationships between
the transitional temperature of
nitric acid condensation (Tc , defined as the
temperature at which the moles of total nitrate in the condensed phases
equals to 5% of the initial moles of nitric acid and determined in this
study.) and logarithm of MEA mole fraction (mol %) in total moles of
RNCs (ammonia and MEA) in the system at 298K. All simulations have the
same total moles of ammonia as 8.86895×10−8 and the
same initial moles of HNO3 and
H2SO4 as
1.11151×10−9 and 2.03777×10−11,
respectively. The system has a fixed initial moles of water vapor as
0.07848 (equivalent to 60% RH at 263.15 K and 101,325 Pa in 1
m3).
