<jats:title>Abstract</jats:title><jats:p>Mathematical models are developed which account for simultaneous heat transfer, mass transfer, and chemical reaction in the oxidation of carbon monoxide over platinum containing monoliths. A two‐dimensional model is shown to predict unusual behavior of the Nusselt number in the presence of rapid reaction. However, a simpler one‐dimensional model is adequate for predicting monolith behavior.</jats:p>
