P14-3B Pure oxygen is being absorbed by xylene in a catalyzed reaction in the experimental apparatus sketched in Figure P14-38. Under constant conditions of temperature and liquid composition, the following data were obtained: To atmosphere H2O 8 02 Xylene Boiling xylene Bi Figure P14-3B Rate of Uptake of O2 (ml/h) for System Pressure (absolute) Stirrer Speed (rpm) 1.2 atm 1.6 atm 2.0 atm 3.0 atm 400 15 31 75 152 800 20 59 102 205 1200 21 62 105 208 1600 21 61 106 207 No gaseous products were formed by the chemical reaction. What would you conclude about the relative importance of liquid-phase diffusion and about the order of the kinetics of this reaction? (California Professional Engineers Exam)
