Modelling of the CSTR seems fairly straight forward, using e.g. Excel, Matlab or Scilab and a simple equation solver to solve for the reaction extents for which the reaction rates match the kinetic expression.

Modelling of the Gibbs reactor requires inclusion of a Gibbs term for carbon. The remaining terms can simply be obtained from G = H - T * S where H = enthalpyF and S is entropyF. Also this can be done in Excel, Matlab or Scilab, using a multi-dimensional minimization (e.g. modify reaction extents so that total Gibbs energy is minimized).

The CSTR uses the reaction phase to calculate the equilibrium constants or reaction rates. In the next version of the reaction specification this will change and the CSTR may be adapted, but, in the current version of the reaction specification, these properties are associated with a phase. Therefore the CSTR is also not an option for multi-phase reactions like these.

What kinetics or equilibrium model do you have? Or do you want to perform a Gibbs minimization?
