the eiementary, isothermal gas phase reaction 13B 5 carried out in a fluidized-bed reactor. The volume of the reactor is 10dm3, and the atalyst density is 50g/dm3. Pure A flows into the reactor at a concentration of 0.1C. nol/ dm3. The catalyst follows a (second-order decays law and independent of oncentration with kd=1sec1. The reaction rate conistant is 0.02dm3/(sec.gcat). Find the volumetric flow rate needed to achicve 50% corrversion, assuming the particle relocity and the gas velocity are the same
