An elementary reaction A+B C+D is to be carried out in a
non-ideal CSTR which has both bypassing and a stagnant region in
this reactor. The measured reactor volume is 1.0 m3 and the flow
rate to the reactor is 0.1 m3/min. The reaction rate constant is
0.28 m3/kmol.min. The feed is equimolar in A and B with an entering
concentration of A equal to 2.0 kmol/m3 k. Calculate the conversion
that can be expected in this reactor if...

(a) A gas phase reaction, ? → ? is carried out in a packed bed
reactor (ID = 0.8 m) containing Al2O3 catalyst. The catalysts were
of spherical shape with a diameter of 6 mm. The reactant A was
diluted with inert (70% inert) and fed to the reactor at 10 atm and
200 °C. The volumetric flow rate was varied from 5 - 15 m3 /s. It
was assumed that the surface reaction and the external mass
transfer influenced...
