2. The elementary irreversible liquid-phase reaction of A+ B C dm mol.min' is carried out with the reaction rate constant of k = 0.5 Consider the startup of a CSTR. The initial concentrations of A and B are 0. 2 and 0.5 mol/dm, respectively. The inlet flow rates of A and B are FAO = FBO = 4 dm/min. The volume of the reactor is V = 10 dm. a. Develop the model equation describing the change of concentrations of components A and B with time for the given constant volume CSTR during startup operation. b. Calculate the concentrations of components A and B at the end of 2 min of reaction using 4th order Runge Kutta Method (Take At = 1).
