Solve numerically (using the Euler and Runge–Kutta methods) the differential equations of the processes describing:

(a) the tank from Problem (7),

(b) the cascade (series) of three isothermal CSTRs where the first order reaction transformation of the A reactant into the B product occurs. The residence time in all reactors is T^R
= V/F = 2 minutes, the reaction rate constant is k = 0.5 min⁻¹, initial concentration in the reactors are C_A1(0) = 0.4 kmol/m³, C_A2(0) = 0.2 kmol/m3 and C_A3(0) = 0.1 kmol/m3, and the step change of the inlet flowrate is from F = 0.8 kmol/m³
to F = 0.6 kmol/m³.
