The following reaction is taking place over a catalyst in a flow reactor at 490C.

A ------->B + C

The reaction rate was obtained at different partial pressures of A, B, and C as shown in the table below.

a)What could be a rate law in agreement with the experimental data given above?

b)We have a postulated reaction mechanism as shown below:

where A, B, and C represent the chemical species and S represent an active site on catalyst, respectively. When the limiting step is found to be reaction (2), what could be a rate law expression? If B and C are very weekly adsorbed or go directly in the gas phase, how does your obtained rate law expression reduce to?

c) What are values for the rate law parameters found in your problem (b)

(d) Plot conversion (up to 90%) and reaction rate as a function of catalyst weight for an entering molar flow rate of pure A of 10 mol/min at an entering pressure P_0 = 10 atm up to a catalyst weight Wmax = 23 kg. (e) Repeat part (d), accounting for pressure drop = 0.03 kg-1 . Plot p and X as a function of catalyst weight down the reactor.
