'Poisoning' a catalyst refers to the process where other substances or compounds inhibit the catalytic activity of the catalyst, reducing or eliminating its effectiveness. This can happen by physically blocking the active sites on the catalyst surface or by forming stable complexes with the catalyst that prevent it from participating in the desired reaction.

What is lindar's catalyst give its use?
Lindlar's catalyst is a finely divided palladium metal deposited on calcium carbonate that is poisoned with lead acetate. It is primarily used for hydrogenation reactions, specifically for selective hydrogenation of alkynes to alkenes under mild conditions. The lead poisoning of the catalyst helps to control its activity, allowing for the desired level of hydrogenation.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
Is copper a catalyst?
yeap, a heat catalyst
What do you call a substance that accelerates the rate of a chemica reaction?
A substance that accelerates the rate of a chemical reaction is called a catalyst.
What does it means by giraffe necking at catalyst tubes?
"Giraffe necking" at catalyst tubes refers to the bending of the tubes due to excessive heat or thermal expansion, causing a bulge in the middle resembling a giraffe's neck. This can lead to reduced efficiency of the catalyst and potential damage to the equipment. It is important to monitor and address this issue to prevent further complications.
What are the advantages and disadvantages of using a catalyst?
Advantages of using a catalyst include increased reaction rate, lower energy requirements, and the ability to lower the activation energy barrier. However, disadvantages can include the cost of acquiring and maintaining the catalyst, potential catalyst poisoning, and the need for specific operating conditions for optimal performance.
What are examples of anti-catalyst substances?
Examples of anti-catalyst substances include inhibitors and poisons that can interfere with or inhibit the catalytic activity of a catalyst. These substances can bind to the active sites of the catalyst or react with the reactants to slow down or prevent the catalytic reaction from occurring.
What is meant by catalist in chemistry?
A catalyst is a substance that speeds up a chemical reaction without being consumed by it.

How can a catclysts life be prolonged?
A catalyst's life can be prolonged by ensuring it is used under optimal conditions, such as the correct temperature, pressure, and flow rates. Regular maintenance and cleaning can also help prevent deactivation or poisoning of the catalyst. Proper storage when not in use can also help extend its lifespan.
Who was poisoning the food on miner details?
Mia was poisoning the food on miner details because her dad owned the vending machines. So by making every one think that the cafeteria food was poisoned, it meant that every one was buying food from the vending machines, which meant that she had enough money to go to modeling camp.
What term describes a substance rhat lowers the amount of energy needed to start a chemical reaction?
This substance is called a catalyst.
What does E-coil mean?
E Coli (assuming that's what you meant) is Esherichia coli, a dangerous bacteria that causes food poisoning.
What is meant by fish and shellfish poisoning?
Paralytic shellfish poisoning (PSP) is a nervous system disease caused by eating cooked or raw shellfish that contain environmental toxins. These toxins are produced by a group of algae (dinoflagellates).
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.
