Analytical solution for the conversion of an isothermal axially dispersed plug flow reactor accomplishing a first order reaction is obtained. Only numerical solution for the conversion of an isothermal axially dispersed PFR accomplishing a second order reaction can be obtained. The Danckwerts boundary conditions for the so-called "closed" configuration are used. For the second order reaction case, we use the shooting method since it is a nonlinear split-boundary-value problem. Damkohler number (Da) and Inverse Peclet number (1/Pe) must have same order of magnitude unless one gets a stiff ODE which cannot be solved easily.
