Two TKSRs with a volume of 400 cm3 are connected in series. The feed concentration is 0.6 molA / L. When the feed rate is 10 cm3 / min, the outlet concentration of the first tank is 0.1 molA / L, when the feed rate is increased to 50 cm3 / min under unfavorable conditions, the outlet concentration of the first tank is 0.35 molA / L. Using these data, find the reaction rate expression. ) A + B ---- R elementary gas phase reaction is carried out in a batch reactor at 100 oC constant temperature and 2 atm constant pressure. The initial concentration contains 30% A, 40% B, 20% inert and 10% R. Speed test 1.52 lt / mol min. It is given as. Find the time taken for B to be 0.20 mole percentage.
