Q2. A 3000 L semi batch reactor is initially full and contains only water. From this state, it is fed with solutions of A and B. The flowrate of the solution with A is 30 L/s and 25 mol/L. The solution with B is 15 L/s and 20 mol/L. The level within the reactor is maintained with an overflow. The reaction is: 2A (aq) + B (aq) C (aq), r = kC15 CB, k = 0.05 L15/mol.5.min a) Derive the balance equations for the concentration of A and B for this reactor (e.g. dCi/dt = ...). b) Plot the concentration of A and B in the reactor from t = 0 to 30 minutes (note the units of flow). This will require numerical integration. c) After a very long time, what will the concentrations of A and B in the reactor approach? This does not require numerical integration but may need to be numerically solved.
