Re: [dwsim-users] reactor application - ethyl acetate

[Daniel W. <dan...@gm...>]

For the existing reactions, you've missed the compound concentrations'
direct and reverse order exponents. You also didn't define the base
compound, which should be the main reactant.

For the conversion and equilibrium reactors, you must define the
corresponding reactions. Kinetic reactions only work with the PFR and the
CSTR.
