The following F curve was obtained from a tracer test on a real reactor
Suggest a model consistent with the F curve.
(a) What are the model parameters a and b?
(b) What is the overall conversion for the second order reaction with CA0 = 2 mol/dm3 and k1 CA0 = 0.1 min–1?
The F curve is consistent with a step input.
step tracer balance on CSTR gives
Junction Balance
nb = fraction of fluid that will be in the reactor a time 10 minutes or shorter, therefore nb = 0.33 no
= t
