(a) A first order liquid phase reaction B S has a rate constant 0.7 s-1 at a temperature of 70C. The reaction occurs in a CFSTR with a volume of 5000 L. The volumetric flow rate of the reaction mixture is 1000 L 3-1 and the concentration of B is 1 mol L-1. Calculate the conversion within the reactor if pure B is fed to the reactor. [7 marks] (b) In order to increase the conversion to 70%, there is a plan of using two additional stirred tank reactors with the same volume as the first reactor, with all three reactors placed in series. Calculate the conversion achieved and state if it reaches the desired value. [10 marks] (c) If the rate constant doubles when the reaction temperature increases by 10C, calculate if a 70% conversion is attained at 80 C when all three reactors are used in series. [7 marks] (d) How many reactors with the same volume (5000 L) would be needed to attain a 90% conversion at 80 C ? [6 marks]
