At time t1 the flow rates to the reactor are switched off. (i) Show that the species balances ( for A and B) for this reactor during 0 the following dimensionless form with initial conditions 0 where 1 1 can be expressed in 0 0 1 1 1 1 2 2 0 , 0 0 k1 k2 k1 k2 1 2 CA , 2 CB , k2 t, k2 0 Q1 , Q2 Q1 (ii) Deduce the appropriate limiting behavior to show how the above equations reduce to the usual batch reactor for 1 . (iii) Take the following values for parameters: 0 10, 0 1, 1, 1, 1 4 then determine the concentration of species and as a func...
