Question 2 Ethylene oxide reacts with water to produce glycol. The reaction is a liquid-phase reaction and carried out in a Continuous Stirred Tank Reactor (CSTR) at 300 K CH-OH HUMO CH-CH:+H₂O CH-OH The concentrations of ethylene oxide and water, entering the inlet streams are 16.13 mol/dm³ and 55.50 mol/dm' with ethylene oxide as the limiting reactant. The specific reaction rate, & is 0.2 mol/dm's at 300 K with activation energy. E of 12500 cal/mol. The ideal gas constant is 1.987 cal/mol K. Assume that the reaction follows an elementary rate law. a. By using a stoichiometric table, express the reaction rate as a function of conversion as below: - = khu (1 – X)(34 -1) (8 marks) b If the volumetric flow rate is "X dm's, calculate the reactor volume (unit: dm') at 80% conversion. (5 marks) C It is proposed to raise the reaction temperature to 350 K to increase the product yield, determine the new reactor volume (unit dm') with the same condition in Q2 (b). (7 marks) d. Space time is the time necessary to process one reactor volume of fluid based on entrance condition. Determine the space time, t at 80% conversion and at 350 K if the volumetric flow rate is "X dm's. Predict the space time if the conversion is decreased and justify your answer (5 marks) (Total: 25 marks) *X is defined as the last three digits of your stadent ID-eg: SUKD1501882, X would be 882 dm's SUKD1500002, X would be 2 dm²/s
