P10-16B The dehydrogenation of methylcyclohexane (M) to produce toluene (T) was carried out over a 0.3% Pt/ catalyst in a differential catalytic reactor. The reaction is carried out in the presence of hydrogen (H2) to avoid coking (J. Phys. Chem., 64, 1559 (1960)). a.

Question
Transcribed Image Text:P10-16B The dehydrogenation of methylcyclohexane
(M) to produce toluene (T) was carried out over
a 0.3% Pt/ catalyst in a differential catalytic
reactor. The reaction is carried out in the
presence of hydrogen (H2) to avoid coking (J.
Phys. Chem., 64, 1559 (1960)).
a. Describe how you would determine the
model parameters for each of the following
rate laws.
kPMPH₂
(1) -rm = kPMPA
(3) −rm=
H₂
(1+KMPM)²
kPMPH,
KPM
(2) -r=
(4) -M
1+KMPM + KH₂
PH₂
1+KMPм
Use the data in Table P10-16B below.
b. Which rate law best describes the data?
Hint: Neither KH, or Kм can take on
negative values.
c. Where would you place additional data
points?
d. Suggest a mechanism and rate-limiting step
consistent with the rate law you have
chosen.
