An irreversible first-order reaction ( A Products) takes place in a recycle reactor. Pure liquid A with an initial concentration of 10mol/it(CA0) is fed to the reactor. The recycle ratio is set on two (R=2) to achieve a conversion of 0.9 in the outlet stream. (a) How much must the initial volumetric flow rate of the feed (0) be changed to keep constant the outlet conversion at 0.9 if the recycle ratio is completely shut off (R=0) ? (b) How much the space time ( ) of the reactor will change if recycle ratio is twice to reach the conversion of 0.9
