A substance that speeds up the reaction is a catalyst. Catalyst examples include sulfuric acid and manganese dioxide. Temperature and light are examples of a catalyst.

Positive Catalyst is a catalyst which increases the rate of reaction. In a wider sense, the term catalyst is used for positive catalyst.

Some examples of a catalyst include enzymes and hormones, basically anything that speeds up a chemical reaction.

DBTL - dibutyl tin dilaurate catalyst is added to polyurethanes as a catalyst to speed up the reaction with moisture and hydroxyl bearing substances.

One of the most common examples of a catalyst is manganese dioxide, which is commonly used for combustion or fro turning hydrogen peroxide into water and oxygen

Methanol to Gasoline 2CH3OH CH30CH3+ H20

Enzymes. (ex. lactase, catalase etc.)

A positive catalyst, or just catalyst for short, are substances that help hasten a chemical reaction. Some typical examples include biological catalysts Amylase, Maltase, Protease, and Lipase; as well as popular chemicals like sulfuric acid and manganese dioxide.

Examples are:- decomposition of CaCO3 by heating- decomposition of hydrogen peroxide with a catalyst- decomposition of organic materials by fermentation

Examples: fine iron powder, vanadium(V) oxide

The correct term is inhibitor.Examples are enzymes inhibitors or acetanilide.

Preservatives as benzoic acid in packed food items act as the negative catalyst or inhibitors.

Well, one would be the Ziegler-Natta catalyst that's used to make polypropylene.

For example the iron oxide catalyst used for synthesis of ammonia.

POSITIVE CATALYST: The substance that increase the speed of reaction is called positive catalyst or catalyst. NEGATIVE CATALYST: The substance that reduces the speed of reaction is called negative catalyst or inhibitor.

Saliva itself is not a catalyst but its contains the enzyme amylase, which is a catalyst.

Catalyst is not a reactant.

what is the purpose of catalyst in textile paint?

No the catalyst is not consumed in the reaction, this is part of the definition of a catalyst.

Enzymes are also catalyst i.e they are biochmical catalyst.

yes, it is. (e.g., it is used as a catalyst in beer and bread). the catalyst is yeastyes all enzymes act as Bio-catalyst

The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.

Enzymes are biological catalysts so Amylase, Maltase, Protease, Lipase. Yeast is also a biological catalyst.

Yes, it is a chemical catalyst.

an example of a catalyst is a light beng turned on and your eyes dialating. the light is a catalyst
