CDP8-DB

Two gas-phase reactions are occurring in a plug-flow tubular reactor, which is operated isothermally at a temperature of 440 and a pressure of 5 atm. The first reaction is first-order:

A B    

and the second reaction is zero-order:

C D+E       

The feed, which is equimolar in A and C, enters at a flow rate of 10 lb mol/s. What reactor volume is required for a 50% conversion of A to B?     (ans.: V=105 )
