What is a catalyst in a chemical reaction?
A catalyst is a compound in chemistry (it can be an acid or temperature or a base or a metal or anything, pressure anything) that shifts the reaction towards one product or the other... In simple words. If you want to obtain something, e.g. water, then you can obtain it in different timings, ie in 2000 years, but if you want to obtain it in 2 hours instead of 2000 years then you add a catalyst, e.g. you heat the reaction to speed it up, you add an acid, or a base etc. Some catalysts also act on the regioselectivity of a compound thru preferring the formation of a stereo-isomer to another. E.g. if you want to obtain S-Thalidomide instead of R-Thalidomide you use a particular catalyst etc...
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
What is the catalytic efficiency of ordinary chemical catalysts?
Different reactions, with the same catalyst, the catalytic efficiency is different. The same reaction, with different catalysts, the catalytic efficiency is also different
Biological enzymes and chemical catalysts of the differences in the source, nature and catalytic characteristics of the different, specific point
Catalyst catalytic reaction relative conditions higher, selectivity than biological enzymes
If possible can anyone give me information on the active site, substrates, products, and the energy of activation as part of the answer?Responses greatly appreciated! Thankss! 10pts to best answer!
Catalysts help shift the equilibrium of a reaction to one that is more favorable. They allow a naturally occurring reaction that may be extremely slow to progress faster or an unfavorable reaction to proceed forward. During the process catalysts are recycled, which means that at the catalyst is the same compound in the beginning and the end of the reaction, although during intermediate steps catalysts can change conformation. Catalysts shift the equilibrium of a reaction by lowering the activation energy of a reaction, which is the energy barrier which must be overcome in order for the reaction to proceed in a desired direction. This can be achieved in several ways such as providing favorable thermodynamic conditions for a reaction or creating intermediates which react more favorably to create the products. Inside the cell a lot of chemical reactions are either too slow to proceed naturally or are simply unfavorable. Catalysts help overcome those barriers. The substrate is the part of the reaction which gets transformed into the products after binding to the active site of the protein.
A catalyst elevates the rate of a reaction by?
lowering the activation energy needed for the reaction to occur.
What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?
Something that can cause a reaction, speed up or slow down a reaction, without changing itself.. structure yea..
What is the chemical nature of the enzyme?
Enzyme is an amphoteric electrolyte, soluble in water, easy to precipitate at the isoelectric point, the enzyme activity-pH curve and the zwitterion of the enzyme. The enzyme is a high-molecular colloidal material, generally can not pass through the semipermeable membrane; Dissociation curve similar to the enzyme in the electric field can be the same as other proteins swimming; ③ lead to protein denaturation factors, such as ultraviolet, heat, surfactant, heavy metals, protein precipitants, etc., can make the enzyme failure; Protease hydrolysis and loss of activity.In addition, the most direct evidence is that all has been highly purified and crystallized enzyme for a primary structure analysis, the results indicate that the enzyme is a protein.
