The gas phase reaction A-2B => 2C, which 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 dm3/min and the feed is equimolar in A and B (and no C). The inlet temperature and pressure are 727C and 10 atm, respectively. The specific reaction rate constant at this temperature is k-4 dm3/mol.min and the activation energy is E=62,000J/mol. a. What is the volumetric flow rate when the conversion of A is 25%? b. What is the concentration of A at the entrance to the reactor? c. What is the concentration of A when conversion of A is 40%? d. What is the reaction rate (-rA) when conversion of A is 40%? e. What is the specific rate constant at 1227C?
