A first-order biochemical reaction takes place in two isothermal CSTRs in series: AkB. The mathematical equations based on mass balance and reaction kinetics are derived as follows: dtdCA1=CA0CA1kCA1dtdCA2=CA1CA2kCA2 Where CA1 and CA2 are the concentrations of the reactant A in the reactor 1 and reactor 2, respectively. The feed concentration is CA0=1.8kmol/m3, and the initial concentrations of component A in the reactor 1 and reactor 2 are CA10=0.4kmol/m3 and CA20=0.2kmol/m3, respectively. The reaction constant k=0.5min1 and the reaction residence =2min. Please use the fourth Runge Kutta method to integrate the ordinary differential equation the ODEs (1) and (2) from t=0 to 2.9 minutes and plot the solutions vs t
