P8-15�� Exothermic reversible reaction with a variable coolant temperature. The elementary reaction
����������� is carried in a PBR that has a heat exchanger surrounding the reactor. The feed is equal molar in A and B with FA0 = 5 mol/s. The coolant surrounding the PBR flow in the same direction as the reactant. The molar flow rate of inerts is equal to that of A. The feed enters at a temperature of 325K and a pressure of 580.5 kPa. Plot X, Xe and T as a function of catalyst weight up to W = 4500 kg, for the base case given below
����������� Additional Information (Base Case)
����������� Vary the following parameters and write a paragraph describing the trends you find for each parameter variation and why they work the way they do. Use the base case for parameters not varied.
����������� Plot T, X, and Xe for the Base Case. Print 6 copies. Next, carry out parts (a) through (f) and vary the parameter above and below the base case and sketch the results directly on the plot for the base case.

����������� *Note:� The program gives QI =1.0. Therefore, when you vary QI, you will need to account for the corresponding increase or decrease of CA0 since the total concentration, CT0, is constant.
