The gas phase reaction A + B → C occurs in a flow reactor. The rate law is given below.

KCACB

-TA

1 + KCA

The initial concentration of A is 1 M and the initial concentration of B is 1.5 M in the feed. k = 0.1

min¹ M-¹ and K = 2.5 M¹¹. The inlet volumetric flow rate is 2 L/min. Assume that the reactors are

isothermal and isobaric./na.

If the reaction takes place in a CSTR, what is the volume of the CSTR that is needed

to achieve 70% conversion?

b.

If the reaction takes place in a PFR, what is the volume of the PFR that is needed to

achieve 70% conversion?

For the remainder of this problem assume that there is an inert gas in the feed with concentration c₁ = 4 M.

c. If the reaction takes place in a CSTR, what is the volume of the CSTR that is needed

to achieve 70% conversion?

d. If the reaction takes place in a PFR, what is the volume of the PFR that is needed to

achieve 70% conversion?

e.

If the reaction takes place in a PFR, what is the volume of the PFR that is needed to

achieve 70% conversion if K = 0.25 M¹¹?
