Cyclohexanol was passed over a catalyst to form water and cyclohexene:
Cyclohexanol → Water + Cyclohexene
The following data were obtained.
Run | Reaction Rate (mol/dm3.s) × 105 | Partial Pressure of Cyclohexanol | Partial Pressure of Cyclohexene | Partial Pressure of Steam (H2O) |
1 | 3.3 | 1 | 1 | 1 |
2 | 1.05 | 5 | 1 | 1 |
3 | 0.565 | 10 | 1 | 1 |
4 | 1.826 | 2 | 5 | 1 |
5 | 1.49 | 2 | 10 | 1 |
6 | 1.36 | 3 | 0 | 5 |
7 | 1.08 | 3 | 0 | 10 |
8 | 0.862 | 1 | 10 | 10 |
9 | 0 | 0 | 5 | 8 |
10 | 1.37 | 3 | 3 | 3 |
It is suspected that the reaction may involve a dual-site mechanism, but it is not known for certain. It is believed that the adsorption equilibrium constant for cyclohexanol is around 1 and is roughly one or two orders of magnitude greater than the adsorption equilibrium constants for the other compounds. Using these data:
(a) Suggest a rate law and mechanism consistent with the data given here.
(b) Determine the constants needed for the rate law. [Ind. Eng. Che111. Res. , 32, 2626-2632 (1993).]
(c) Why do you think estimates of the rate law parameters were given?
