. A first-order irreversible reaction: A B is taking place in a continuous stirred-tank reactor (CSTR) with a volumetric flow rate of 10 L/min. The reaction rate constant is 0.02 min^-1 and the feed concentration of A is 1 mol/L. What is the volume of the reactor required to achieve 90% conversion? 2. Consider a gas-phase reaction: A + 2B → C [10] that takes place in a packed-bed reactor (PBR) with a catalyst volume of 0.2 L. The feed rate of A is 0.1 mol/s and the feed rate of B is 0.2 mol/s. The reaction rate constant is 0.01 L/(mol*s) and the pressure drop across the catalyst bed is 2 bar. What is the conversion of A at the exit of the reactor? (Hint use Ergun equation) [15] Question 2 [40 Marks] 1. A first-order reversible reaction AB is taking place in a plug-flow reactor (PFR) with a feed concentration of 2 mol/L and a flow rate of 0.5 L/min. The rate constant for the forward reaction is 0.02 min¹¹ and the rate constant for the reverse reaction is 0.01 min¹¹. What is the length of the reactor required to achieve 80% conversion of A? [15] 2. Consider a batch reactor with a volume of 100 L that is initially charged with a mixture of A and B at a mole ratio of 2:1. The reaction A + B → C is first-order with a rate constant of 0.01 min¹. What is the time required to achieve 90% conversion of A? [15] 3. Explain how helpful it is knowing the desired conversion in the initial stages of designing a reactor. [5] 4. What technical and economic advantages does a PFR have as opposed to a CSTR. [5] .
