A 3rd order irreversible reaction takes place in a PFR reactor. The flow entering the PFR has a concentration of A of CA0. The volumetric flow rate is a constant, v0, and the reaction rate constant is kA. Please derive a relation between the concentration of A (CA) with respect to the volume of PFR, V. Draw a diagram of 1/CA2 vs. V. PLOT THERE IS NO TABLE PROVIDED assume numbers

The degradation of atrazine can be described by second-order kinetics with k= 5 L∙mg-1min-1 in a reactor. Calculate the volume of a PFR and CSTR required to remove atrazine to the MCL if the flow rate is 2 m3/min and C0 is 0.06 mg/L. Assume steady-state. If it costs $1/gal of tank and $4/gal of tank for a CSTR and a PFR, respectively, determine which type of reactor would be cheaper to construct.

Note: Assume that the volumetric flow rate does not change with
reaction extent; when one reactant is in large excess, it is
reasonable to assume constant volumetric flow rate, especially for
liquid-phase reactions. You can only find KCbVr/Q that would yield
the desired 50% conversion in a single CSTR!

The elementary gas phase reaction (A <--> 2B) is to be carried out in an adiabatic CSTR. The feed which is at a temperature of 27oC, consists of 80% of A and the remainder inerts. The volumetric flow rate entering the reactor at this temperature is 100 l/min. The concentration of A in the feed at 27oC is 0.5 mol/liter. For 80% of the adiabatic equilibrium conversion, calculate the required reactor volume. DATA: CpA=12 J/mol.K; CpB=10 J/mol.K; CpI=15 J/mol.K deltaHrxn=-75000...
