28.3 A mass balance for a chemical in a completely mixed reactor can be written as Vdtdc=FQckVc2 where V= volume (12m3),c= concentration (g/m3),F= feed rate ( 175g/min),Q= flow rate (1m3/min), and k= a second-order reaction rate (0.15m3/g/min). If c(0)=0, solve the ODE until the concentration reaches a stable level. Use the midpoint method (h=0.5) and plot your results. Challenge question: If one ignores the fact that concentrations must be positive, find a range of initial conditions such that you obtain a very different trajectory than was obtained with c(0)=0. Relate your results to the steady-state solutions
