Negative catalysts (inhibitors) are those substances (or factors) which slow down the chemical reactions by decreasing the required activation energy for the reaction, for example the decomposition of Hydrogen peroxide may be slow down by adding a small amount of Glycerin in it.

What is meant by 'poisoning' a catalyst?
It means decreasing the efficiency of the catalyst, and slowing down the reaction. The chemicals used for this are called Inhibitors, although it may not contain any poisons or toxic chemicals
What is it called when you slow down a chemical reaction?
This is called an inhibitor or negative catalyst
What does a catalyst do in a chemical reaction?
Reduces the activation energy of the reaction, which speeds up the progress of the reaction It increases the rate of a chemical reaction. However a true catalyst is not consumed in the reaction.
What is an example of an enzyme catalyst?
I just did a lab on this in school and for an organic catalyst we used sand. Also just to help an example of an inorganic catalyst would be Manganese Dioxide (MnO2). Hope this helps!
What is a real life example of using a catalyst?
Catalysts - digestive enzymes, saliva, laundry stain removers2. Inhibitors -food preservations, substances in slow-release medications, refrigeration
What is the difference between positive catalyst and negative catalyst?
The substances which increase the rate of a chemical reaction are called a Positive Catalyst whereas The substances which decrease the rate of a chemical reaction are called Negative Catalyst. Positive Catalyst decreases the Activation energy of reactant molecules whereas negative catalyst increases the Activation energy of the reactant molecules. Positive Catalyst is also called the Promoter whereas negative catalyst is also called Inhibitor.
Do all chemical reactions involve catalyst or inhibitors?
no

What is the difference between an inhibitor and catalyst?
Catalyst speeds up reactions, and inhibitors are used to slow down reactions.
What is a substance that interferes with a catalyst?
An inhibitor is a substance that interferes with a catalyst. Inhibitors also interfere with other biologic activity such as growth.
What are AADC inhibitors also called?
They are also called DC inhibitors
What are DC inhibitors also called?
They are also called DC inhibitors
What does a catalyst do in a chemical reaction?

What are ACE inhibitors also called?
They are also called Angiotensin-converting enzyme inhibitors
What are Angiotensin-converting enzyme inhibitors also called?
They also called ACE inhibitors
Differentiate a positive catalyst from a negative catalyst?
A positive catalyst is a catalyst which speeds up the rate of a chemical reaction by lowering its activation energy. A negative catalysts slows the rate of a chemical reaction or makes it less likely to occur.
