The optional equilibrium constant coefficients have been

automatically retrieved from the Aspen Plus reactions database.

The Aspen Plus reactions database contains over 600 reactions,

which cover virtually all common electrolyte applications.

4 Click to the right of the Equilibrium reaction field to select

another equilibrium reaction and view the equilibrium

constants.

The second equilibrium ionic reaction is for HCL dissociation.

There are no equilibrium constant coefficients for this reaction.

Instead of calculating the equilibrium constant directly, Aspen

Plus will calculate the chemical equilibrium from the Gibbs

free energy of the participating components.

The reaction for NACL(S) precipitation and its equilibrium

constant coefficients are also available on this sheet.

1 In the Equilibrium constants for option, select Salt.

2 If you had additional salt dissolution reactions you could click

< and > to view them, but since there is only one salt, these

buttons are unavailable.

For the complete dissociation reaction of NaOH, no constants are

shown. Since this is a complete dissociation reaction, it does not

require an equilibrium constant.

If you had your own equilibrium constant coefficients, you would

enter them directly on this sheet. If you had additional reactions to

include, you would enter them on the Stoichiometry sheet and

then perhaps add equilibrium data here.
