Q:What is the analytical principle of chemical adsorbents?
What do you mean by the chemical adsorber? BET is the use of the surface of the uneven force field, but the inert gas at low temperature in the surface adsorption. TPD, TPR is the number of active centers that can be measured by the technique of desorption and reduction between specific gases and catalysts as the temperature increases. If the active site is a reduced position, H2-TPR can be used. If the active site is acidic, NH3-TPD can be used, but also the method of alkali titration.
Q:how does the AMOUNT of a catalyst affect reaction rate?
theoretically, the more catalyst there is, the faster the rate of reaction. this is because it is bringing more particles together quicker.
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:Which branch of chemistry or what specialty can study the catalyst
Inorganic Chemistry: Preparation, Synthesis, Structure and Catalytic Reaction of Inorganic Catalysts and Catalyst Carriers
Q:What are the roles of enzymes (protein catalysts) in catalyzing biochemical reactions in the cell.?
To make it simple unlike the dude above me...enzymes (biological catalysts) lower the activation energy, which speeds up the reaction. EVERY reaction needs a little boost of energy--the activation energy--and enzymes lower that.
Q:What is catalyst in Science?
not all catalyst are enzymes. There are biological catalysts as well as non biological ones catalysts are something that speeds up the rate of a chemical reaction without itself getting altered after it. for example an enzyme is a catalyst because it speed up the rate of food digestion (by breaking down food molecules) and doesn't get altered after the reaction.
Q:catalyst and reagents ???
Believe me, nema, there's no way that we chemists know the best catalyst for every reaction. That would be simply impossible. However, from the type of reaction, the reactants, products, reaction conditions, solvents, etc. and from one's experience and the literature (papers and patents) one can get a good idea for most reactions of the type of catalyst that has worked for similar systems. One then starts off with a catalyst from the literature and modifies or changes it if improvement is needed based on chemical principles that one learns. There are also some theoretical calculations that can be made. Sometimes they work and sometimes they don't :) If it is an industrially important process like the Haber process for making ammonia from nitrogen gas and hydrogen gas, there may be thousands of catalysts which have been tried and evaluated. New minor improvements are being made every day. When a company does find a very good catalyst for an important reaction, often they keep it a trade secret. The good catalyst can make a huge difference in how commercially successful a particular process is. That's a large part of what chemical engineers do. You may never know if you have the best catalyst. The most you can hope for is one that is good enough. So it's a few parts personal knowledge, a few parts literature, a couple of parts theory, a lot of experimentation and often, more than not, a little luck. :)
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:What is the microcosmic principle of the catalytic reaction in the chemical reaction?
The catalyst reduces the activation rate of the reactants by increasing the reactant density of the reaction conditions and making the chemical reaction easier.
Q:Gene cloning of heat - resistant bacteria
The specificity of enzymes is very strict, those compounds that are considered symmetric in organic chemistry such as glycerol, ethanol, citric acid, etc., are asymmetric (even with the same groups) when they are used as substrates for enzymes, That is, their location in space, after all, different (available "three-point landing" theory explained, 1948 Oqston proposed).
