2. The elementary liquid-phase reaction A+B (reversible) C is to be carried out adiabatically in a set of tubular reactors packed with a resin catalyst and arranged in series. The feed consists of 25 mol% A, 25 mol% B, and 50 mol% inerts at 300 K. There are available to you a large number of interstage heat exchangers that can cool the reaction stream to temperatures as low as 300 K. The reactors have sufficient catalyst to reach 95% of the corresponding equilibrium conversion. (a) What is the smallest number of reactors in series necessary to obtain an exiting conversion above 50 % ? (b) What would you need to do to increase the conversion to 95 %? (c) What concerns would you have about reaching to 95 % conversion?
