Q:A biological catalyst or a chemical reaction facilitator is know as a/an?

I was always taught that it was something best learned by putting forth a bit of effort, reading a bit and embedding the info in your brain so you will remember it always. Just me I guess.

Q:what is metallocene catalyst technology?

Metallocene catalyst A transition-metal atom sandwiched between ring structures having a well-defined single catalytic site and well-understood molecular structure used to produce uniform polyolefins with unique structures and physical properties. See also Catalysis; Coordination chemistry; Coordination complexes; Metallocenes; Organometallic compound. In the early 1980s, W. Kaminsky discovered that an appropriate co-catalyst activated metallocene compounds of group 4 metals, that is, titanium, zirconium, and hafnium, for alpha-olefin polymerization, attracting industrial interest. This observation led to the synthesis of a great number of metallocene compounds for the production of polymers already made industrially, such as polyethylene and polypropylene, and new materials. Polymers produced with metallocene catalysts represent a small fraction of the entire polyolefin market, but experts agree that such a fraction will increase rapidly in the future. See also Polymer; Polymerization; Polyolefin resins.

Q:What is the catalyst condition in the chemical equation?

On the middle of the equal sign or arrow above ah ~

Q:Chemical catalyst system baa?

Catalyst is divided into inorganic catalyst and organic catalyst organic reaction generally need more catalyst, such as concentrated sulfuric acid

Q:How the catalyst accelerates the chemical reaction

Reduced the activation energy required to reflect

Q:Does the catalyst affect the chemical reaction rate constant? How does the chemical reaction rate constant change when a positive catalyst is added to a reaction?

The catalyst will change the rate constant

Q:No one knows the expression of the catalyst and the chemical expression of the acridine

If it is potassium permanganate oxygen, the catalyst is only manganese dioxide, so write on the horizontal line MnO2

Q:How does the catalyst affect chemical balance? Why the catalyst has no effect on the chemical equilibrium, for v-t diagram

Chemical reaction to reactor molecules to reach a certain amount of energy in order to react, this energy is the activation energy of the reaction. While the material energy in nature can be obtained by probability statistics

Q:The addition of the catalyst has no effect on the chemical equilibrium of the movement

The essence of chemical equilibrium is a dynamic equilibrium. Under certain conditions, the equilibrium constant of the reaction is a certain value. The role of the catalyst is to reduce the activation energy required for the reaction, increase the number of activated molecules, and increase the number of molecules per unit time , But the positive reaction is positive for the reaction, so do not change the speed.

Q:In the chemical reaction will have to use the catalyst reaction, such as H2O2 === (MnO2) H2O + O2 ↑, then the catalyst in the end to participate in the reaction (that is, the catalyst itself is the reactant) If so, why are some of these substances in the reaction (these substances refer to the catalyst) in the reaction after the quality and nature of the change does not change?

The definition of a chemical reaction rate in a chemical reaction can be changed (accelerated or slowed down) in a chemical reaction, and the quality and chemical properties of the substance itself are not catalyzed before and after the reaction (which will change during the reaction) Also known as catalyst. Its physical properties may change, for example, MnO2 in the catalytic potassium chlorate to generate potassium chloride and oxygen before and after the reaction from the block into a powder. There is also a saying that the catalyst reacts first with one of the reactants and then the two products continue to undergo a new chemical reaction under the original conditions and the reaction conditions of the catalyst reaction product are more favorable than the reaction conditions of the original reactants Changed.
