Consider the pair of reactions in which ethylene is oxidized either to ethylene oxide (desired) or to carbon dioxide (undesired) in the furnace: C₂H4+O₂-C₂H4O C₂H₁+30₂2 CO₂ + 2H₂O The feed mixture and air are fed at a temperature To. All gaseous effluents are at temperature T emerging from the non-isothermal reactor. a) Calculate the number of degrees of freedom of the process. How would the answer differ if the reactor were adiabatic? b) Outline a manual calculation procedure to determine the compositions of all streams.
