Langmuir-Hinshelwood Reaction in a Plug Flow Reactor

Oxygen oxidizes CO to COon a supported metal catalyst in an isothermal plug flow reactor. Use buttons to select plots of "partial pressures" (P), "surface coverages" (θ), or "reaction rate" as a function of distance down the reactor. Use sliders to vary the "temperature", the "CO feed partial pressure", and the "O2 feed partial pressure". Because the rate-determining step is the reaction of adsorbed CO and adsorbed O, and because CO adsorbs more strongly than O2, increasing the CO feed partial pressure can decrease the rate of C2 formation. This happens when the CO surface coverage becomes much higher than the O surface coverage.
