- Q: Chemical catalyst system baa?
- Can speed up or slow down the reaction rate without participating in the reaction of the material
- Q: What is a catalyst and how does it make a reaction go faster?
- Wohoo i stil remember this from last year! A catalyst is a substance that speeds up the chemical reaction without being used up in the reaction itself e.g. manganese dioxide in the making of oxygen. And.. A catalyst works by providing a convenient surface for the reaction to occur. The reacting particles gather on the catalyst surface and 1) collide more frequently with each other 2) more of the collisions result in a reaction between particles because the catalyst can lower the activation energy for the reaction. A catalyst is often used as a powder, so that it has a bigger surface area per gram. Okay i copied the last bit from my science book but i remembered the first bit!! HA!
- Q: why is palladium/platinum a good catalyst?
- Palladium and platinum can form partial bonds with other molecules. By forming these partial bonds, the bond in the actual molecule gets weaker and weaker and hence, the bond becomes easier to break. Let's say for example a hydrogen molecule. There is a single bond between the 2 hydrogen atoms. Platinum/palladium will form partial bonds with the 2 hydrogen atoms. By doing so, the single bond BETWEEN THE 2 HYDROGEN ATOMS gets weaker and weaker. Hence, a smaller amount of energy is needed to break the bond between the 2 hydrogen atoms (the hydrogen molecule). As the amount of energy needed to overcome the bond between the 2 hydrogen atoms gets smaller, we say the activation energy for the reaction has been reduced. Hence, a greater amount of bonds in hydrogen molecules can be broken in a smaller time, and therefore, we say palladium/platinum has catalysed the reaction.
- Q: What is a catalyst?
- In industrial production, the large amount of catalyst used frequently, the catalyst that does not change theoretically may sometimes change into another substance, which is the so-called poison of catalyst,
- Q: describe a biological catalyst?
- Enzyme are biological catalyst, proteinous in nature, formed in animal's body by exocrine cell, present in inactive form, generally ends with suffix ase e.g enterikinase with exceptions pepsin, specific in nature not only speed up biological reactions but also lower down the reactions inside the body.
- Q: What is the chemical nature of the enzyme?
- Enzyme protein and cofactor are present in the absence of catalytic activity, only these two parts together to form a complex to show the catalytic activity of this complex called the whole enzyme. Some enzymes cofactor is the metal ion, some enzyme cofactor is Organic small molecules in these organic small molecules, where the enzyme and protein binding is called the auxiliary base; and with the enzyme protein binding was more relaxed, dialysis can be used to separate the enzyme protein is called coenzyme. There is no strict boundary between the base and the coenzyme, the role of the metal ion in the enzyme molecule, or as a component of the active site of the enzyme, or the conformation necessary to form the center of the enzyme, or between the enzyme and the substrate The same coenzyme is often able to bind to a variety of different enzyme proteins, the composition of a variety of catalytic functions of different enzymes, such as coenzyme Ⅰ (NAD +) can be a variety of enzymes, As a coenzyme for many dehydrogenases, but each enzyme protein can only bind to a specific coenzyme into a whole enzyme.It can be seen that the specificity of the enzyme is the enzyme protein part of the coenzyme in the enzymatic reaction is usually responsible for electrons, atoms Or some chemical groups to determine the nature of the reaction.In recent years, it has been found that, in addition to proteins, some RNA and DNA molecules also have a catalytic effect on the chemical nature of the enzyme is the concept of protein produced a strong impact . However, the now known enzymes are essentially protein-based, or protein-dominated core components, and the concept that the enzyme is a protein-based biocatalyst does not exclude the presence of other types of catalysts, and more precisely, Can be given to the enzyme under the definition of: the enzyme is a kind of biological activity and special space conformation of biological macromolecules, including protein and nucleic acid.
- Q: I opened catalyst control center to see what its was, i didn't change anything and now when i full screen a youtube and hulu the screen will be black and the loading bar at the bottom will be stuck. I also noticed that now when i play minecraft all the blocks have a black out line i cant get rid of. I tried deleting my .minecraft and that didn't fix it.
- on the backside suitable hand corner of the small reveal, there's a field with a smaller field in it (suitable of the quantity), press that, it provides you with the finished reveal. you could press the comparable button once you opt for to bypass decrease back. The button would have a crimson X in it this time.
- Q: Chemical catalyst in several ways
- In general, positive catalyst (accelerated rate) and negative catalyst (slowing down)
- Q: Will the catalyst be able to increase the rate of chemical reactions?
- Not necessarily
- Q: Just something I've always wondered about...
- activation energy has got nothing to do with this. the main reason that the transition metal oxides are catalysts is that they have vacant d orbitals. the reagents are adsorbed on the metal surface and the d orbitals serve as a sort of clamp between the substrates and reagents. for example if you consider the hydrogenation of ethylene in palladium catalyst here the d orbitals lead to syn addition of hydrogen by clamping the pi electron cloud . this is a sort of chemisorption.
