Considering this homogeneous gas reaction A→3R that follows second-order kinetics. For a feed rate of 6 m3/hr of pure. A at the pressure of 5 atm and at a temperature of 350 degree celsius ,an experimental reactor consisting of a 2.5 cm ID pipe 2 m long give sixty percent conversion of feed. A commercial plant is to treat 320 m3/hr of feed consisting of 50 % A, 50% inerts at 25 atm and 350ºC to obtain eighty percent conversion. Determine how many 2-m lengths of 2.5 cm ID pipe are required?
