Problem 1. For an irreversible liquid phase reaction 2A -> B, the reaction rate is of the 2nd order with respect to the reactant concentration CA. The concentration-dependent reaction rate is plotted below. This reaction is performed in a cascade of two identical CSTRS (same reactor size and temperature). The inlet concentration of A of the 1st CSTR is 2 mol/L. The outlet concentration of A of the 2nd CSTR is 1 mol/L. The inlet flow rate of the 1st reactor is 100 L/h. Please use the graphical method to determine the outlet concentration of A of the first CSTR and the size of each CSTR. Please briefly show the procedure for reactor size calculation.

Problem 1. For an irreversible liquid phase reaction 2A -> B, the reaction rate is of the 2nd
order with respect to the reactant concentration CA. The concentration-dependent reaction
rate is plotted below. This reaction is performed in a cascade of two identical CSTRS (same
reactor size and temperature). The inlet concentration of A of the 1st CSTR is 2 mol/L. The
outlet concentration of A of the 2nd CSTR is 1 mol/L. The inlet flow rate of the 1st reactor is
100 L/h. Please use the graphical method to determine the outlet concentration of A of the
first CSTR and the size of each CSTR. Please briefly show the procedure for reactor size
calculation.
