Question

Which is an example of a heterogeneous catalyst?
amylase
catalytic converter
food preservatives
amino acids

Answer 1

An example of a heterogeneous catalyst is a catalytic converter. A catalytic converter is an emissions control device that converts toxic pollutants in exhaust gas to less toxic pollutants by catalyzing a redox reaction (oxydation or reduction). 

Answer 2

Answer:

catalytic converter

Explanation:

A heterogeneous catalyst is one that has a phase different from the reactant molecules. A catalyst speeds up a chemical reaction by lowering the activation energy required to start the reaction. But a catalyst does not undergo any change in the chemical process. Catalysts in a catalytic converter are metallic palladium or platinum that react with the hydrocarbons and carbon monoxide from the exhausts of a car to form carbon dioxide and water.
