(1) Temperature (180 - 330 K): (See inputs for details of restrictions on the temperature range, related to the chemical composition of the system.)
(2) The water content of the system must be specified as either a (fixed) ambient relative humidity or the number of moles of water present per m3 of atmosphere. Select one:
Now enter the relative humidity (range 0.1 - 1.0) or moles of water present:
(3) If the temperature is less than 273.15 K, and you wish the system to be equilibrated to the water vapour pressure over ice, then check the box here. (If constant total water has been selected then this option has no effect.)
Check the boxes below to disable the partitioning of selected trace gases into the vapour phase. (The default for each gas is that partitioning is calculated.)
Prevent partitioning of the following gases:
No boxes should be checked for any systems containing both NH4+ and Cl− ions.
Omit the following solids:
