As discussed in the text, the reaction of CO and Cl2 to form phosgene obeys the rate expression r=kCCOCCl23/2 (a) Find an expression for CCOCl2 versus in a CSTR for stoichiometric feed assuming constant density. (b) Find an expression for CCOCl2 versus in a PFTR for stoichiometric feed assuming constant density. (c) Repeat these calculations (or at least set them up) for pure feeds with no diluent assuming all species are ideal gases
