How are a, b, c, and d determined in this equation? ln(keq)=A+B/T+C*LN(T)+D*T

ln(keq)=A+B/T+C*LN(T)+D*T. When carrying out a reaction, it is necessary to enter these values, but they cannot be found; I would like to know whether these values can be looked up or whether they need to be calculated manually

I was working on a absorption tower, and I couldn’t find any parameters related to ionic reactions in its built-in database, so I had to enter them manually: NH3+HSO3-====NH4++SO3--

Generally, it involves looking up a table; it’s impossible to calculate it by oneself.

Which table do I need to check to find this?

First, you need to find the corresponding kinetic parameters based on the reaction equation

Does this require using reaction kinetics parameters or not?

Hello, is the electrolysis reaction formula you customized displayed in the electrolyte guide?

Aspen provides the equilibrium constants for common ionization reactions; you can use Aspen’s electrolyte generation wizard to have them generated automatically. If such values are available in Aspen, they will be filled in automatically
