Safety:
As a matter of good industrial hygiene, gloves and safety glasses with side shields or better eye protection should be worn when handing Carbon Black ,For more information, refer to the MSDS.
- 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: Will the catalyst change the reaction rate in the chemical reaction?
- Many of the catalysts are specific in varying degrees, and when added to the chemical reaction system that it can catalyze, it must change the rate of chemical reaction, and of course both positively and negatively catalyzed. Chemical reaction rate, it can not be called a catalyst.
- Q: The role and significance of chemical catalysts
- The catalyst changes the reaction rate of other substances, the single said to increase the reaction rate, but before and after the reaction of chemical properties and quality unchanged, can be used repeatedly
- Q: It is best to tell me what the role of sulfuric acid in these reactions, respectively
- Esterification reaction (dehydration), nitration (dehydration, concentrated nitric acid), carbonation reaction or dehydration reaction (organic matter in sulfuric acid blackening, dehydrating agent), sulfonation reaction (dehydrating agent), ethylene (dehydrating agent).
- Q: What is the difference between biological enzymes and chemical catalysts?
- Chemical catalysts are widely used, generally the majority of transition elements
- Q: Does the catalyst slow down the chemical reaction rate? Still can only accelerate
- As far as I know, depending on the definition of the catalyst to reduce the activation energy can only accelerate the reaction rate. However, some substances can reduce the rate of reaction, for example, to dilute the reaction solution to slow down the reaction rate, but slow down the general mention of the catalyst.
- Q: Will the catalyst change in the chemical reaction?
- The catalyst is actually involved in the chemical reaction, the catalyst is added to the reaction, becomes the other material, and then the reaction becomes back, and appears to have no change, actually involved in the change, but the end result the catalyst did not change
- Q: Does anybody have any tips or references I can go to for this? I'm writing a novel and the main character wants to be a catalyst; the story isn't about him and his journey, so much as the effects on everyone around him that come about simply because of him being there and being who he is. How would I go about doing this, and doing it well?
- Ways to be a catalyst: By his behaviour: - He is a good listener. People use him as a sounding board and make important decisions as a result. - He is indiscreet and inadvertently reveals people's secrets and back-sniping comments. - He is a ****-stirring gossip. - He is a home-wrecking Lothario. - He is wise and gives good advice. - He is a hooligan who ruins businesses with vandalism, costs people their jobs and ruins relationships by beating people up. - He is a manipulative, blackmailing bastard who tries to turn every woman into a prostitute and con every man out of his money. - He is a charlatan who preaches nonsense about religion, health and business investments. By effortlessly influencing other people's behaviour: - He is famous and people try to impress him wherever he goes. - He has cancer or a disabling war wound. People admire and pity him and are shocked by his PTs mood wings. - He is gay, Muslim or a suspected paedophile and people want to persecute or cure him. - He is destitute. People argue amongst themselves over whether it's because he's lazy, has bad karma or there but for the grace of God go I. - He really looks like Jesus, Buddha or Santa and the sight of him makes people contemplate their Humanist values, coming to various conclusions. Perhaps you can write about his reputation; how he earned it, how it precedes him and provokes prejudices that he sometimes confirms or disproves. Use a detached, omniscient God-narrator. (Pretend Morgan Freeman's reading the audiobook.) Alternatively perhaps he is not a catalyst but a neurotic voyeur, fascinated by the minutiae of other people's lives so that the mundane appears tumultuous. He is not influencing people but your account of the changes in people's lives are centred on his observation of them.
- Q: I have just spent CAN$550 to replace a catalyst converter at one end of the muffler. The repairman said I need to replace the oxygen sensor very soon, otherwise, the C.C. will be gone again. Is that true... can someone confirm this for me. Thanks.
- The oxygen sensor senses whether the exhaust coming out of the engine is clean of emissions gasses. It can also alter the air-fuel mixture in the engine to run leaner or richer. And yes, it's always a good idea to change the oxygen sensor when changing the c.c. because it can damage the c.c or other components in your engine.
