The irreversible, gas$-$phase reaction A$+$B P occurs over a heterogeneous catalyst. This reaction is proposedto follow the Langmuir$-$Hinshelwood mechanism assuming the surface reaction is slowest step.Experiments with a differential reactor have been used to measure the rate of reaction. The results are shownas below table.$-$ Are the data consistent with the proposed L$-$H mechanism?$-$ Under the experimental conditions, do you expect that the catalyst surface mainly consists of vacant sites,sites with adsorbed A$,$ sites with adsorbed B$,$ or sites with adsorbed P$?$ Justify your answers.$\backslash$table
