". 2- The gas-phase reaction b) c) d) 2A + 4B → 2R Which is first order in A and first order in B is to be carried out dm³ min.' isothermally in PFR. The entering volumetric flow rate is 2.5. 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 dm³ temperature is 4 and activation energy is 15,000 cal/mol. mol.min a) What is the volumetric flow rate when the conversion of A is 25%? 3- What is the rate of reaction at the entrance to the reactor (i.e., X = O)? What is the rate of reaction when the conversion of A is 40%? What is the value of the specific reaction rate at 1227"C?
