Experimental data for the gas-phase catalytic reaction A+BC is shown below. The limiting step in the reaction is known to be irreversible, so that the overall reac- tion is irreversible. The reaction was carried out in a differential reactor to which A, B, and C were all fed.

Hint: Sketch (- ) as a function of P, as a function of Pb, and as a function of Pc. (b) From your rate expression, which species can you conclude are adsorbed on the surface? (c) Suggest a rate law and then show that your mechanism is constant with the rate law in part (a)
