Unformatted text preview: 2 and 21 mol% O 2 . 2. Lactic acid (CH 3 CHOHCOOH) reacts with hydrogen to give 1,2-propanediol (CH 3 CHOHCH 2 OH) and water. The reaction, which takes place in the gas phase, is: CH 3 CHOHCOOH + 2H 2 = CH 3 CHOHCH 2 OH + H 2 O The reactor feed rate is 50 mol/h lactic acid, 150 mol/h H 2 , and 100 mol/h of an inert. The reactor pressure is 5 atm and at the reactor temperature, K a = 3 . 2atm-1 . (a) What is the fractional conversion of lactic acid if the reactor outlet is at equilibrium? (b) If you want to increase the fractional conversion of lactic acid at equilibrium would you recommend increasing or decreasing the reactor pressure? (c) If you decreased the inert feed rate, would the fractional conversion at equilibrium increase, decrease, or remain unchanged? 1...
