- Q: Carbon dioxide and hydrogen in the catalyst and heating conditions, the reaction of water and methane, the chemical equation is what
- CO2 + 4H2 = catalyst, heating = 2H2O + CH4
- Q: The best use of chemical catalysts
- Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
- Q: The catalyst before and after the reaction of the quality and nature of the same, does it mean that a little catalyst can be all the substrate reaction? Such as: one gram of MnO2 can reflect the infinite H2O2?
- Catalyst before and after the reaction of the same quality,
- Q: why is palladium/platinum a good catalyst?
- Platinum As Catalyst
- Q: How are the 4 characteristics of a catalyst (1. organic or inorganic 2. reusable 3. Highly specific, and 4. lowers activation energy) important in preforming life functions? please be as specific as possible, i understand that these are characteristic, i just don't understand why they're beneficial, other than the reusable and lowers activation energy one.
- Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
- Q: Why can't catalysts make an unfavorable reaction favorable?Can anyone give me a relatively simple explanation for this?Thank you so much in advance!
- Catalysts, as enzymes, only change the activation energy (the energy the compound needs to gain to transform into products), they don't change the Gibbs energy values of reactants nor products. Therefore, if the delta G of the reaction is positive, it'll still need free energy to complete. They make a reaction complete faster than in normal conditions, but don't change the actual possibility for that reaction to happen. In the human body, a lot of reactions of catabolism have a positive G value and these reactions needs to get energy from other coupled reactions that have a negative value, so the total value is still negative. Many of them use hydrolysis of ATP to provide that energy, as its hydrolysis is about -30 kJ/mol in physiological conditions. I don't know what class you're in to ask this question, so can't really know if this answer is too simple or complicated for u... sorry in advance! Jo?l
- Q: what is a catalyst ?
- anything that speeds up a reaction, chemical or otherwise, between two things
- Q: The role of catalyst in chemical reactions
- The role of the catalyst is to change the reaction required to achieve the activation energy, can reduce the activation energy is called positive catalyst (that is, usually the meaning of the catalyst), to improve the activation energy is negative catalyst
- Q: What is the difference between biological enzymes and chemical catalysts?
- Biological enzymes are an environmentally friendly biocatalyst with greater superiority. Such as the reaction speed, processing conditions (such as temperature, PH value, etc.) more moderate, safe and easy to control the operation and can replace the strong alkali and other chemicals. The biological enzymes act only on specific substrates, with little damage to the substrate and the biodegradation of the treated wastewater to reduce water and energy consumption. After more than a century of research by scientists, more than 3,000 known enzymes are generally considered. The application of biological enzymes in the textile industry, initially the application of α-amylase in cotton fabric desizing process, and later developed into the cellulase used in denim washing and bio-polishing process, and now the development of pectinase to the biological scouring Technology, hydrogen peroxide enzyme catalytic decomposition technology, protease in silk and wool fiber applications
- Q: What kind of chemical substances can seriously damage the ozone layer, as a catalyst or reactants can be?
- Freon decomposition of free radicals. The destruction of our ozone is mainly caused by him. Chlorine free radicals are also available.
