The symbolical reaction is as follows:

$A+2BC+D$

Experimentally determined reaction rate has a form: $r=k{C}_A{C}_B$ and reaction rate constant $k=0,04\frac{m^3}{\frac{\text{m}\text{o}\text{l}}{s}}$

The reaction described above is carried out in the plug flow reactor, resulting in the product molar flow rate $Fc=100\frac{\text{m}\text{o}\text{l}}{h}.$ Entering concentrations of substrates $C_{A0}=1\frac{\text{m}\text{o}\text{l}}{m^3}$ and $C_{BO}=4\frac{\text{m}\text{o}\text{l}}{m^3}$

a$)$ What are the volume of the PFR$,$ space time and volumetric flow rate if the assumed conversion $=0,75?$

b$)$ What are the volume of the PFR$,$ space time and volumetric flow rate if the assumed conversion $=0,8?$
