Q:What is catalyst in Science?
A catalyst is a substance that increases the rate of a reaction by decreasing the activation energy (energy required to start the reaction). It does so by creating a new reaction mechanism (the way the reaction happens on a molecular level) that happens more easily and with less energy. For example, a catalyst could attract both reactants, thus bringing them directly together and facilitating the reaction.
Q:What is the difference between a catalyst and an inducer in a chemical reaction?
The catalyst does not participate in the reaction, but only the carrier of the reaction; the inducer will participate in the reaction
Q:What does what does catalyst mean?
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:In the chemical reaction, the rate of decomposition reaction is related to the quality of the catalyst?
There are relationships
Q:Are biological enzymes harmful to humans?
Biological enzymes through scientists more than a century of research, usually known as more than 3,000 kinds of enzymes, the current application of biological enzymes in the textile a wide range of technology, fiber modification, silk degumming, raw hemp (ramie, linen, Kenaf) degumming, dyeing and finishing of the desizing, refining, finishing and net cleaning processing, textile printing and dyeing wastewater treatment and garment processing and other aspects of the application. Enzyme technology has a unique advantage in improving dyeing and finishing processes, saving energy, reducing environmental pollution, improving product quality, adding value and developing new raw materials. At present in the textile processing using a wide range of enzyme preparations are mainly cellulase, protease, amylase, pectinase, lipase, peroxidase, laccase, glucose oxidase eight categories.
Q:What happens to this catalyst ?
Only a catalyst? Poor catalyst. Catalysts get very little respect. Folks assume that catalysts don' do anything, yet they magically speed up a reaction without taking part in the reaction. That just isn't the case. Most chemical reactions take place in multiple steps. A catalyst can be a reactant in one step and a product in s subsequent step, thereby giving the impression that it did not react. The catalyst speeds up a chemical reaction by providing an alternate reaction pathway which has a lower activation energy. The lower activation energy means that more molecules will have the energy required to react, and the rate will be greater. So the bottom line is that the catalyst will have appeared not to have reacted, and returns to its original state.
Q:What is the PTC catalyst in chemistry?
1, polyether chain polyethylene glycol: H (OCH2CH2) nOH chain polyethylene glycol dialkyl ether: R (OCH2CH2) nOR2, cyclic crown ethers: 18 crown 6,15 crown 5, Fine and so on. 3, quaternary ammonium salt: commonly used quaternary ammonium salt phase transfer catalyst is benzyl triethyl ammonium chloride (TEBA), tetrabutyl ammonium bromide, tetrabutylammonium chloride, tetrabutylammonium hydrogen sulfate (TBAB) , Trioctylmethylammonium chloride, dodecyltrimethylammonium chloride, tetradecyltrimethylammonium chloride, and the like. 4, tertiary amine: R4N X, pyridine, tributylamine and the like. 5, quaternary ammonium base (its alkaline and sodium hydroxide similar) soluble in water, strong hygroscopicity. 6, quaternary phosphonium
Q:what is a catalysts and how can they be useful?
A catalyst is a substance that speeds up the rate of a chemical reaction with itself being chemically unchanged at the end of the reaction. They are useful as they help to lower the minimum amount of energy needed ( also known as activation energy) to start the reaction. Hence, by lowering the activation energy of the reaction, they help to speed up the rate of reaction. For example, in the Haber process for the manufacture of ammonia, the catalyst iron is added to speed up the rate of reaction between hydrogen gas and nitrogen gas. Otherwise, the reaction would have proceeded much more slowly. Another example is the catalyst nickel used in the manufacture of margarine and vanadium (V) oxide for manufacturing sulfuric acid. As catalyst remain chemically unchanged after a reaction, they can be reused again and hence, they are required in minute amounts. An example is the washing powder used in washing clothes, they help to remove food stains by digesting the proteins in food. They can be reused after each reaction and hence, you do not need to add in the whole packet of washing powder but only a few spoonful.
Q:what is the difference between enzyme and catalyst?
Enzymes and catalysts both affect the rate of a reaction. The difference between catalysts and enzymes is that while catalysts are inorganic compounds, enzymes are largely organic in nature and are bio-catalysts. Even though all known enzymes are catalysts, all catalysts are not enzymes. Moreover, catalysts and enzymes are not consumed in the reactions they catalyze. Catalysts are low molecular weight componds, enzymes are high molecular globular proteins. Catalysts are inorganic, enzymes are organic. Catalyst reaction rates are slower (usually) than enzyme reaction rates. Catalysts are not generally specific - enzymes are VERY specific. Catalysts increase or decrease the rate of a chemical reaction, enzymes are proteins that incrase the rate of chemical reactions & convert the substrate into product. There are 2 types of catalysts - (positive & negative), and the 2 types of enzymes are activation enzymes and inhibitory enzymes. Catalysts are simple inorganic molecules, while enzymes are complex proteins.
Q:Does the catalyst participate in chemical reactions?
The catalyst does not participate in the chemical reaction, it only plays an auxiliary role.
