Best Answer

Ziegler-Natta catalysts are heterogeneous catalysts composed of transition metals and organometallic compounds, while metallocene catalysts are homogeneous catalysts consisting of a single transition metal atom sandwiched between two cyclopentadienyl ligands. Metallocene catalysts are more precise and produce polymers with narrower molecular weight distribution compared to Ziegler-Natta catalysts.

What is the catalyst for the reaction between isoprene and hydrogen?

The catalyst for the reaction between isoprene and hydrogen is typically a metal catalyst such as platinum, palladium, or nickel. These catalysts help facilitate the reaction by lowering the activation energy required for the reaction to occur, thus speeding up the process of hydrogenation of isoprene.


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.


Identify the metal used as the catalyst in the Haber process?

Iron is the metal typically used as the catalyst in the Haber process.


What is the difference between an enzyme and a catalyst and how are they similar. Please be very specific for me?

An enzyme is a type of biological catalyst, which means it speeds up chemical reactions in living organisms. Enzymes are specific to the reactions they catalyze and are usually proteins. Catalysts, on the other hand, are substances that speed up chemical reactions without being consumed in the process. Both enzymes and catalysts lower the activation energy required for a reaction to occur, increasing the rate of reaction.


Why catalyst required when hydrogen reacts with iodine?

A catalyst is required when hydrogen reacts with iodine to help break the strong bond between hydrogen molecules, allowing them to react with iodine more readily. The catalyst assists in lowering the activation energy required for the reaction to occur, thereby increasing the rate of the reaction.

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.


What is the main difference between a heterogeneous catalyst and a homogeneous catalyst?

The heterogeneous catalyst is not mixed with the reactants.


What is the difference between an inhibitor and catalyst?

Catalyst speeds up reactions, and inhibitors are used to slow down reactions.


What is the difference between enzymes and catalyst?

There is no difference. An enzyme is a natural catalyst. Catalysts speed up the rate of reaction without being used up itself.


What is the difference between a catalyst and an inhibitor?

Catalyst: a substance which promote and help a chemical reaction. Inhibitor: a substance which greatly reduces the rate of a chemical reaction.


The difference between catalyst and inhibitor?

A catalyst lower the activation energy (speeds up the reaction) while an inhibitor increases the activation energy (slows it down).


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 relationship between an enzyme and a catalyst?

enzymes and catalyst both are the substance which increase the rate of reaction several 100 to 1000 times. Both are specific in temprature and for substratethe only difference between them is that enzymes are found in livingbeings or we can say that enzymes are biological catalyst

What is the relationship between a catalyst and an inhibitor?

A catalyst speeds up a reaction and an inhibitor slows down a reaction


What is the difference between a precatalyst and catalyst?

Pre-catalyst is a catalytic converter that is fitted to Diesel engines to control emissions soon after engine start up when the main catalytic converter is not yet up to operational temperatures. In Europe a pre-catalyst is commonly used where a Diesel Particulate filter is fitted for stage 4 and 5 emissions requirements. The DPF is placed upstream from the main catalyst and in turn prevents the main catalyst heating up quickly enough to control the very initial emissions.
