1. A first-order irreversible reaction: AB is taking place in a continuous stirred-tank reactor (CSTR) with a volumetric flow rate of 10 L/min. The reaction rate constant is 0.02min1 and the feed concentration of A is 1mol/L. What is the volume of the reactor required to achieve 90% conversion? [10] 2. Consider a gas-phase reaction: A+2BC that takes place in a packed-bed reactor (PBR) with a catalyst volume of 0.2L. The feed rate of A is 0.1mol/s and the feed rate of B is 0.2mol/s. The reaction rate constant is 0.01L/(mols) 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]
