Oxidation of Naphthalene to Phthalic Anhydride

Derivation

      For negligible volume change with reaction . Therefore neglect mole change, the

                                                                       FT = FT0

      Calculate the mean molecular weight

                  

                                                                    

                                                                   

                                     

                                                              

      For constant total pressure and PA = P0yA, we multiply by the total pressure P0
