Heterogeneous Catalysis
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A heterogeneous catalyst exists in a different phase, usually solid, furnishing a surface where adsorbed reactants react before desorbing.
Show
A car's catalytic converter uses a solid metal surface to convert gaseous carbon monoxide and nitrogen oxides into carbon dioxide and nitrogen.
Watch for
A heterogeneous catalyst's action happens at its surface only — surface area, not total mass, is what speeds the reaction.
