What catalyst is used in making polyesters?
The catalyst commonly used in making polyesters is an esterification catalyst, such as an acid catalyst like sulfuric acid or an organic acid like p-toluenesulfonic acid. These catalysts help facilitate the reaction between the diol and the dicarboxylic acid to form the polyester polymer.
How is a catalyst like platinum different from an enzyme?
A catalyst like platinum is a non-biological substance that speeds up chemical reactions by providing an alternative pathway with lower activation energy. Enzymes, on the other hand, are biological catalysts that are specific to certain reactions and are essential for biological processes. Enzymes are made up of proteins and can be regulated by the cells that produce them, while catalysts like platinum are typically inorganic and do not have this level of specificity or regulation.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What are enzymes used for?
it is a protein to speed up a reation. it is like a catalyst.
What is linlard's catalyst?
Linlard's catalyst, commonly referred to in the context of chemical reactions, typically pertains to a specific type of catalyst used in organic synthesis, particularly in the hydrogenation processes. It is a metal catalyst, often involving elements like palladium or platinum, that facilitates the addition of hydrogen to unsaturated organic compounds. This catalyst is known for its effectiveness in increasing the reaction rate and improving yield in various chemical transformations.

What is the catalyst for ammonia?
The catalyst for the production of ammonia through the Haber-Bosch process is typically iron with a promoter like potassium oxide or alumina. This catalyst helps lower the activation energy required for the reaction to convert nitrogen and hydrogen into ammonia.
What are enzymes used for?
it is a protein to speed up a reation. it is like a catalyst.
Where is the catalyst?
I've never heard of a vehicle that has a catalyst. A catalyst is like a bridge itallows things to happen. I think you are thinking of a catalytic converter. This is the box around your exhaust pipe and it is used for partially reducing the toxicity of emissions from the combustion of gasoline
Which does a catalyst not change?
Catalyst is not a reactant.

Catalyst vs one without catalyst What is different?
what is the purpose of catalyst in textile paint?
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.
What is the difference between a homogeneous catalyst and a heterogeneous 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.
