Hello. Please help me with this problem.

The irreversible isomerization of n-pentane to i-pentane (A>B) follows an elementary rate law and the gas phase reaction out in mixed flow reactor (MFR). The rate dependent only on n-pentane and the following data was obtained: Table 2 Experimental data for irreversible isomerization of n-pentane to i-pentane T (s) 14 25 29 30 27 24 25 12 CAO (mol/dm³) 200 100 90 190 180 170 150 140 120 110 CA (mol/dm³) 80 70 50 40 20 10 a) Using data from Table 2, suggest the best single flow reactor (either CSTR or PFR) for 85% conversion when the feed rate consists of 100 mol/dm3 of n- pentane. Justify your answer. b) If two-reactor scheme to be installed in the system, proposed the best reactor arrangement for the same conversion in (a) that give optimum condition. Justify your answer. Hint: Determine the concentration of reactant between stages at minimum reaction rate.
