I have attached a set of kinetic equations that I need to design a cstr with. They are in terms of mole fraction and I have been stuck on which way to go about it as aspen does not allow me to put these equations in. I have tried rearranging them into the form of the LHHW expression after removing the acceleration term to simplify them but equation 1 & 5 have different power adsorption terms so cannot be rearranged into this form and I have no experience using fortran subroutines so reluctant to go down that route. Equations 1-3 are series reactions and reaction 4 is a side reaction and equation 5 & 6 are reactants. My supervisor has told me that it's simple to do so I think i am missing something and this is my last resort as I have no one else to ask due to online learning. Any suggestions would be very helpful, thanks
