Question 3 (20 points): Answer the following based on the equilibrium conversion for AB as shown in the figure below: (a) Is the reaction exothermic or endothermic? (b) Assume the reaction will run in an adiabatic plug flow reactor with an inlet temperature of 450K. Can you sketch how the temperature will change as the reaction is progressing in this reactor? (c) Can you list 3 ways to achieve a 90% target conversion considering that the inlet temperature is at 450K and adiabatic reactor operation? Comment on the advantage and disadvantages of each option very briefly
