2. Consider the elementary reaction 2A2B is carried out in a reactor which the catalyst decays by sintering with catalyst decay constant kd=0.04min1. Pure A is fed to the reactor at a concentration of 0.2mol/dm3 and a molar flow rate of 5.0mol/min. Given specific reaction rate k=1.0dm6/(molkg catmin). Wha catalyst weight is necessary to achieve 50% conversion for a catalyst loading rate of 5kg/min ? 3. Discuss the following in brief: ahExplain the inhibition in term of: i. Foreign substance-competitive inhibition (3 marks) ii. Noncompetitive inhibition (3 marks) b. Describe the enzyme competitive inhibition kinetics. Include the competing mechanism for the same site on the enzyme. (4 marks)
