Question 4 (15 Marks) We learned in class that the PFR volume required is the area under the curve while the CSTR volume required is the rectangular area. Based on the processed data in Table 4.1, the plot me as a function of X is presented in Figure 4.1. Also, based on the plot FM as a function of X is presented in Figure 4.1, the PFR volume required was - 2.17 mto obtain 80% conversion. 0.2 0.4 0.6 0.7 0.8 Table 4.1.
