Crystals have a high ability to adsorb gaseous substances present in the air.
In the decomposition of potassium chlorate by heat, manganese dioxide plays the role of a heterogeneous catalyst.
In the catalytic hydrogenation of alkenes, the size of the catalyst particles has no effect on the reaction rate.
In the decomposition of $\text{N}_2\text{O}$ on a $\text{N}_2\text{O}$ surface, doubling the concentration of $\text{N}_2\text{O}$ keeps the reaction rate constant.
