Sulfur dioxide is oxidized to sulfur trioxide in a small pilot-plant reactor. SO2 and 100% excess air are fed to the reactor at 450C. The reaction proceeds to a 65% SO2 conversion, and the products emerge from the reactor at 550C. The production rate of SO3 is 1.00 10^2 kg/min. The reactor is surrounded by a water jacket into which water at 25C is fed.

(a) Calculate the feed rates (standard cubic meters per second) of the SO2 and air feed streams and the extent of reaction, .

(b) Calculate the standard heat of the SO2 oxidation reaction, H r (kJ). Then, taking molecular species at 25C as references, prepare and fill in an inletoutlet enthalpy table and write an energy balance to calculate the necessary rate of heat transfer (kW) from the reactor to the cooling water.

(c) Calculate the minimum flow rate of the cooling water if its temperature rise is to be kept below 15C.

(d) Briefly state what would have been different in your calculations and results if you had taken elemental species as references in Part (b).
