4. Fogler P5-11B (Fifth edition) The irreversible elementary gas phase reaction: A +B- C+D Is carried out isothermally at 450 K in packed bed with 200 kg of catalyst. 15 atm 2.5 atm The entering pressure is 15 atm and the exit pressure in 2.5 atm. The feed is 40% A and 60% B on a molar basis with FAO = 10 mol/min and CAG - 5 mol/dm . Currently 87% conversion is achieved in the reactor. a) . What will be the conversion if catalyst particle size is tripled without changing any other parameters b) What will be the conversion if catalyst particle size is halved without changing any other parameters
