Consider a reaction of species A to form product B in a constant-density isothermal system. The rate of disappearance of A is given by a second-order rate, that is, (-rA) = kCA2. A process plant carries out the reaction using a single PFR with 95% conversion of A. To increase production, a second reactor is added. The second reactor is to have the same volume as the first one, and the overall conversion from the system of two reactors is...
