(6) Compare a CSTR with a PFR below. a. A flow of 0.3 m3/s enters a CSTR (volume of 200 m3) with an initial concentration of species A at 200 mg/L. The reaction proceeds with 1st order kinetics and a reaction rate of 5.09 hr-1. Determine the concentration of species A leaving the reactor. (8 pts) b. If a plug flow reactor was designed to have the same efficieny as the CSTR in Part A, what would the volume of the PFR be

Explanation:

Given that:

The flow rate Q = 0.3 m³/s

Volume (V) = 200 m³

Initial concentration = 2.00 ms/l

reaction rate K = 5.09 hr⁻¹

Recall that:

where;

Thus; the concentration of species in the reactant = 102.98 mg/l

b). If the plug flow reactor has the same efficiency as CSTR, Then:

The volume of the PFR is ≅ 140 m³

hey there!

mass = 6.75 g

volume =   9 cm³

therefore:

d = mass / volume

d   = 6.75 / 9

d = 0.7 g/cm³

answer b

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.

hope it ,
