Q:What is a Catalyst?
Catalysts are something that will speed up a reaction. Catalysts are usually acids but platinum catalysts are used in the industrial production of nitric acid (4 NH3 + 5 O2 ---4 NO + 6 H2O). Vanadium pentoxide is used as the catalyst in the industrial manufacture of sulfuric acid (S + O2 ---SO2. 2 SO2 + O2 ---2 SO3) The catalyst is used to make the reaction between sulfur dioxide and oxygen A LOT faster. Catalysts are also used in explosives. The most common is sulfuric acid (eg. nitroglycerin, TNT, nitrocellulose). Weaker acids like citric acid is used in the synthesis of HMTD, an organic peroxide. Hydrochloric acid is also a commonly used catalyst. Manganese dioxide can be used as a catalyst to generate oxygen when added to potassium chlorate or hydrogen peroxide. (2 H2O2 + MnO2 ---2 H2O + O2 + MnO2 (it is not necessary to include the catalyst in an equation, however). (2 KClO3 + MnO2 ---3 O2 + 2 KCl + MnO2).
Q:What is the nature of the chemical catalyst?
Catalyst is the chemical reaction can change the reaction rate of other substances, and its own quality and chemical properties in the chemical reaction before and after the material has not changed Some catalyst can really slow down the reaction rate, the book said only refers to the usual circumstances , In general, junior high school and high school teaching into the do not do special instructions are understood to speed up the reaction rate. It is only necessary to know that the catalyst is not only used to speed up the reaction rate. Once the reversible reaction reaches equilibrium, adding the catalyst does not break the balance, but at the same time accelerates the forward and reverse reaction rates. The degree of acceleration is the same.
Q:Gene cloning of heat - resistant bacteria
The process of metabolism in the body contains many complex and regular material metabolism and energy changes.Green plants and certain bacteria use solar energy, water, CO2 and inorganic salts and other simple substances, after a series of changes, the synthesis of complex sugar, Fat, protein and other macromolecules, and animals and the use of these plants in the material, and through the complex decomposition and synthesis, the reaction into their own part of the need to grow, breeding, etc. In the laboratory, complex The synthesis and decomposition of organic matter must be carried out under severe conditions such as high temperature, high pressure, strong acid and alkali, such as starch and protein hydrolysis, and some reactions are difficult to carry out in vitro, such as protein synthesis, but in biological conditions Mild (370C or so, near neutral pH), these reactions can be carried out smoothly and quickly.For example, animals eat meat in the digestive tract only a few hours will be completely digested and decomposed; bacteria in the appropriate conditions, Twenty minutes to proliferate generation, in this short twenty minutes, the synthesis of new cells within the need for all the complex substances, etc., what is the reason? This makes the chemical reaction in the body easier And the root cause of rapid progress is the prevalence of a catalytic role in the body of the protein - enzyme.
Q:catalysts used in the industry :D?
i will tell you the hydrogen and carbonmonixide production in indsutry they will use alumina based nickel catalyst for adsorption of gases, at high temperature it will breaks as small molecules like hydrogen, co2, co,ch4, after they will separate them using carbon molecular seives as catalyst. another catalyst for hydrogenation of double bond is copper chromate for sulphur removal from disel and petrol they will use COMOX ( copper and molybdinum catalyst ) after then pass through zinc sulfide with hydrogen gas , the sulfur will removed as a hydrogen sulfide.
Q:The properties of scandium
Sci-Scandium (Sc) Basic knowledge Introduction In 1879, Swedish chemistry professor Nelson (LFNilson, 1840 ~ 1899) and Clive (PTCleve, 1840 ~ 1905) were almost simultaneously in rare mineral silica beryllium yttrium and black The mine found a new element. They named this element "Scandium" (scandium), ...
Q:What is the principle of catalyst reaction rate in chemical reactions?
Whether the chemical reaction can be carried out according to the change of free energy, but only according to the change of free energy can not determine whether the reaction can be completed, because the chemical reaction is also completed by the reaction of the energy barrier, that is, if the reaction energy barrier is high, To provide some energy, across the barrier, to complete the reaction. The energy barrier is called activation energy. And the role of the catalyst is to reduce the activation energy, so that in a relatively harsh environment, chemical reaction occurs.
Q:How are a catalyst and an intermediate similar? How are they different?
A catalyst speeds up the rate of a reaction by lowering the activation energy barrier which is, presumably, the energy required to achieve the reaction intermediate. Catalysts are also not consumed in the reaction, they are regenerated towards the end. A reaction intermediate is a configuration that a molecule takes prior to achieving it's lowest energy form which would signify the end of the reaction. Intermediate usually are hard to isolate because of the incentive to go to the most stable configuration. How are they different? A catalyst is not a part of the reaction product and it doesn't get consumed. An intermediate in a reaction is transformed into the product. How are they similar? Well, catalysts drive the reaction and make it easier for the reaction for follow through. Since intermediates are high energy and thermodynamics tells us that low energy is favorable, the incentive for a high energy intermediate to drive down to it's stable for can also drive a reaction. I hope that helps. I hope it makes sense.
Q:Describe the role of a catalyst..........?
a catalyst lowers the activation energy of a reaction. By lowering the activation energy, the internal kinetic energy the reactants become sufficient for the reaction to occur on a much larger scale and thus appear faster. Without the catalyst, you would depend on the statistical probabilities of small numbers of reactant particles having enough internal kinetic energy to overcome the activation barrier. a substrate is merely the substance in the reaction being catalyzed
Q:When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
No, the catalyst is written above the equal sign, not the reactants, nor the product
Q:What are the examples of chemical catalysts used in life?
Clothing. "New synthetic fiber made of clothing, soft and comfortable and cheap and durable. Cloth from natural fibers to man-made fibers, and then to the development of synthetic fibers, dyes from the original natural dyes to the current synthetic dyes, reactive dyes , All reflect the contribution of chemistry to the development of clothing, chemical clothing from the initial cover utility, into today's beautiful, convenient, with a special function of the utility, it greatly enriched the style of clothing, material, use
