The gas-phase reaction 2A + 4B →2C is first-order in A and first-order in B is to be carried out isothermally in a plug-flow reactor. The entering volumetric flow rate is 2.5 L/min, and the feed is equimolar in A and B. The entering temperature and pressure are 727°C and 10 atm, respectively. The specific reaction rate at this temperature is 4 L/mol·min and the activation energy is 15,000 cal/mol. (a) What is the volumetric flow rate when the conversion of A is 25%? (b) What is the rate of reaction at the entrance to the reactor. (c) What is the rate of reaction when the conversion of A is 40%? (d) What is the concentration of A at the entrance to the reactor? (e) What is the concentration of A at 40% conversion of A? (f) What is the value of the specific reaction rate at 1227°C. Ans: 1.875 L/min b) A 1.485×10-2 mol/L.min c) A=4.95x10-3 mol/L min d) CAO 0.0609 mol/L e) CA=0.0609 mol/L f) k 49.53 L/mol·min
