A) The liquid phase reaction A --> 2B + C takes place isothermally in a batch reactor of volumev = 7500 L. The batch cycle time (tc = t + td) is considered to be fixed by a shift period of 8 hours. If the downtime (td) between batches is 45 minutes, calculate the rate of production of B (mol/hr) on a continual basis, with 1 batch per shift, if the feed concentration (CA0) is 3 mol/L. The rate of reaction is given by (-ra) = kCa ^1.5 where ka = 0.0025 L ^0.5 mol^-0.5 min^-1

B) you are asked to examine the possibility of increasing the rate of production of B by uncoupling tc from the length of the shift period. If all else remains unchanged, what would you recommend? Assume that the reaction A is relatively valuable.
