The reactions   A  →  B, A--->X and A-----> Y

Is to be carried out isothermally in a continuous-flow reactor. Calculate optimum volume of CSTR in liters at maximum selectivity of B when the entering molar flow rate is 5 mol/h assuming the reaction rate –rA is:

 

rx = k1 with k1 = 0.05 mol/h.L

 

rB = k2CA with k2 = 0.0001/s

 

ry = k3CA^2 with k3 = 3 L/mol.h

 

The entering flow rate is 10 L/h.
