Mass flow per unit of volume differential equation

Dear Sir or Madam, I am trying to solve the differential equation I am presenting here. As an initial approach I will assume that the pressure and temperatures are constant, but as you can see in the second equation the density of the solid in this iteration depends on the mass adsorbed in the previous iteration (equations are shown below). So far I have tried to solve it using Global ODEs and DAEs to solve the differential equation and Domandain ODEs and DAEs to try to extract the value of the previous iteration and insert it in the calculation of the variables. But I don't get any results, could you give me some suggestions on how to do it? Thanks. Best regards.

Hello Jose,

It does look like your equations came through as you expected.
