Consider a reaction where A is converting to B. A B The reaction is known to be of first order and irreversible. Laboratory data were collected for this reaction, which is presented below in Table 1. Conversion (XA) Rate of disappearance of A (-ra) mol m-³ s-1 This data is now to be used to calculate the volume of an industrial scale CFSTR when the feed rate of into the reactor is 0.4 mol s-¹. Table 1: 0.0 0.1 0.2 0.4 0.6 0.7 0.8 0.450 0.370 0.300 0.195 0.113 0.079 0.05 (a) Using mass balances for a CFSTR, derive a graphical method to calculate the volume of the reactor using the data available, i.e., feed rate, conversion and reaction rate. (b) Determine the volume of the industrial reactor to achieve a conversion of 65%. (c) If a PFR were used to achieve this conversion, would the volume of the reactor be the same? Explain your reasoning.
