is carried out in a real reactor

a volumetric flow rate of 2 dm3/min. The following F(t) was determined
from a trace test
Calculate the conversion

The reaction A ->
B with rate law is carried out in a real reactor
that has the following F-curve. The entering concentration of A is 2 molar with
a volumetric flow rate of 2 dm3/min. The following F(t) was determined
from a trace test
Calculate the conversion using
1) the segregation model
2) the maximum mixedness model
Explain the difference in conversions between the two
models.
1) Xseg = 0.83 [see attached polymath codes]
2) Xmm = 0.83 [see attached polymath codes]
Both models predict the same conversion! The reason is: for reaction order 0 < n < 1, max mixedness predicts higher conversion and for n > 1, segregation predicts higher “X”. In this case, the reaction goes from 0 order to 2nd order as CA decreases. Thus, the predictions of the tow models average out.
