The CH 4 physisorption reaction and O 2 dissociative adsorption are the most sensitive reactions, a↵ecting most of the metal surfaces in the carbon and oxygen binding energy space explored, for both CMPO and CMPO-BMA models. Significant trends can be viewed across the metals, showing that these reactions are mostly responsible for the shapes of the descriptor heat maps. This suggests that incorporating BMA rates does not modify which reactions are the most sensitive reactions that dictate the shape of the descriptor heat maps.
