(b) The irreversible liquid phase first-order reaction A B with k = 0.03 dm .S mol (10 marks) is carried out in a CSTR. The entering concentration of A, CAO, is 2 molar and the exit concentration of A, CA is 0.1 molar. The entering and exiting volumetric flow rate, vo, is constant at 3 dm/s. What is the corresponding reactor volume? What happened to the reactor volume when the reaction is changed to second-order? Justify the changes. (10 marks)
