- 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:What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- The principle of the catalyst: the catalyst is mainly by reducing the activation energy, so that the reaction is easy to carry out, so as to achieve the catalytic effect.
- Q:High chemistry: Does the catalyst affect the heat and heat of the reaction?
- No effect
- Q:What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?
- The catalyst can change the activation energy of the chemical reaction, thereby changing the reaction rate.
- Q:Why is the catalyst in the chemical balance, the rate of change and balance?
- But the positive reaction rate is accelerated, but also speed up the reverse reaction rate, the two increase the same multiple, so the system is still in a stable state, the same balance.
- Q:Does the catalyst participate in chemical reactions?
- The catalyst only acts as a catalyst in the chemical reaction and does not participate in the chemical reaction
- 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:The beginning of the chemistry plus the catalyst and the plot without the Cuihua agent
- Activated molecular map
- Q:Organic chemical concentration of bromine and liquid bromine What is the difference between the conditions in the iron as a catalyst can not be reacted with toluene to produce tribromotoluene? Is it possible to work with phenol to produce tribromophenol?
- The concentrated bromine water is a bromine aqueous solution and the liquid bromine is pure bromine. Only liquid bromine can produce tribromotoluene, and to add iron powder as a catalyst, and the main production is to lead bromotoluene and p-bromotoluene, tribromotoluene this content is very small.
- Q:chemistry subject
- copper nickel zinc common catalysts are solid acids such as the silicas, alumina, and zeolites it depends on the reaction
