It is desired to design a reactor for the catalytic oxidation of formaldehyde (CH2O).

The chemical reactions are:

and

The reaction must be carried out in a tubular reactor. [1] Determine the system of differential equations and sketch the graph of molar flows and concentrations of compounds in the reaction medium over the (volume) of the reactor. Assume that there is no head loss. The reaction temperature is 300 K and is isothermal. Use Polymath.
