Question

why does a reaction involving a catalyst finally stop

Answer 1

When the catalyst is a reaction is removed by the reaction, this reaction will stop as there won't be any agent causing it anymore. !

Answer 2

Answer:

Explanation:

Catalysis is a process that accelerates chemical reactions due to molecules called catalysts, which provide ways to reach products that require less energy.

A catalyst intervenes in the reaction mechanism, but is not consumed. This means that the catalyst participates in some stage of the reaction, but then regenerates.

In addition, a catalyst is used in a small amount: a minimum mole percentage, with respect to reagents, is usually required to observe an increase in velocity.

There are three types of catalysis:

• Homogeneous: the catalyst is present in the same phase as the species that react.
• Heterogeneous: the catalyst and reagents are in a different phase.
• Enzyme: occurs only in living beings, and in these cases the catalysts are enzymes.

The absence of a catalyst can make the reaction so slow that it never occurs. Therefore, when the catalyst of a reaction is removed, the reaction may stop.
