- Q: No one knows the expression of the catalyst and the chemical expression of the acridine
- In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.
- Q: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q: The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?
- The morphology of the catalyst may change before and after the chemical reaction, but the quality and chemical properties of the chemical reaction do not change before and after the chemical reaction. It is noteworthy that this does not mean that the catalyst is not involved in chemical reactions. Some chemical catalysts are involved in chemical reactions, but in the form of intermediates, consume a certain amount of catalyst in a chemical reaction, but in the subsequent chemical reactions, the same quality of the catalyst will be produced. On the whole, the quality of the catalyst before and after the chemical reaction is not changed.
- Q: A catalyst elevates the rate of a reaction by?
- lowering the activation energy needed for the reaction to occur.
- Q: and what type of macromolecule are they made of? thanks!
- by definition a catalyst is a substance that alters the cost of, or makes accessible, a chemical or biochemical reaction yet maintains to be unchanged on the tip of the reaction. Enzymes are the only organic biochemical catalysts. Ribozymes are a particular sort of enzymes. certainly, the definition of enzyme rates: organic and organic catalyst produced in cells, and able to dashing up the chemical reactions mandatory for all times. they're great, complicated proteins, frequently soluble, and are noticeably specific, each and every chemical reaction requiring its very own specific enzyme. The enzyme's specificity arises from its energetic website, a community with a shape such as portion of the molecule with which it reacts (the substrate). the form of the enzyme the place the chemical binds in straightforward terms facilitates the binding of that distinctive chemical, such as a particular key in straightforward terms working a particular lock (the lock and key hypothesis). The enzyme and the substrate slot jointly forming an enzyme–substrate complicated that facilitates the reaction to ensue, and then the enzyme falls away unaltered. In prepare maximum catalysts are used to velocity up reactions. There are different non-organic and organic catalysts. maximum of that are utilized in industry and are commonly transition metals or their compounds.
- Q: What are the methods of catalyst characterization?
- Chemical means, according to the different detection methods, methods are different, but is to explain the chemical properties, chemical structure characteristics.
- Q: and can you give me an example of it .. please give it in easy terms if you can. thanks
- a catalyst enables a reaction to occur quicker, by lowering the activation energy, and finding it an alternate path way to react. example of a catalyst is an enzyme, found in our saliva, it helps us digest our foods, by breaking it down into smaller pieces.
- 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.
- With a four cylinder engine, the code definition should have read: B1S1 (for the upstream sensor responsible for fuel/air ratio monitoring) or B1S2 (for the sensor downstream of the catalytic converter, which only monitors that part). If you changed the front (S1) sensor and you still have a code for it, save your old sensor as there may be nothing wrong with it. If the code is for the O2 sensor heater, check your fuses. If not, the code is probably a symptom of another problem, such as a misfire, restricted fuel filter or intake air leak. Is this the same code you got previously? Did you install a direct-fit replacement or a universal sensor that had to be configured for your honda's wiring connector?
- Q: Why would the Eact decrease if a catalyst is added?
- A catalyst by its very nature increases the rate of reaction by binding to a reactant, hence changing its shape and reactivity with other reactants. However, the catalyst is neither consumed nor will it change the chemical shape of the products.
- Q: What are the characteristics of the catalyst in the catalytic reaction?
- The role of the catalyst in the chemical reaction is to change the rate of chemical reaction, and its own quality and chemical properties do not change.
