2. Data for the gas-phase dissociation of sulfuryl chloride, SO,Cl, into chlorine, Cl, and sulfur dioxide, so, at 279.2 C are presented below. The total pressure method was employed to follow the course of the reaction. Under constant volume conditions the results were as follows: (min) 28.1 41.1 54.5 3.4 15.7 96.3 68.3 82.4 (mm 345 Hg) 395 323 325 335 355 365 375 385 (a) What reaction order do these data suggest? (The conversion is 100% at infinite time). (b) Using the results from part (a), design a PFR to achieve 75% conversion of a feed of 1 gmol/min of an equimolar feed of SO,CI, and inerts at 279.2 C.
