The gas phase elementary reaction : 2A + B 3R + 2S taking place at 450K and in a constant pressure batch reactor of 2 atm. Starting with 40%A, 50%B and 10% inert, previous experiments showed that an increase in total volume of 30% was recorded in 25 mins. a) What is the half-life of A? b) What is the % increase in total volume if 18 Batches can be completed per day and 40 mins is spent for dumping, cleaning and start-up in between batches? d) If the same reaction is conducted at 450K at a constant total volume with an initial total pressure of 2.5 using the same feed composition, how many minutes will it take to reach a 35% increase in total pressure?
