- Q: What is the principle of the catalyst? Why can change the rate of chemical reactions and their own without any change
- Because the catalyst does not participate in the reaction, it can change the rate of chemical reactions without any change in itself.
- Q: why is palladium/platinum a good catalyst?
- Palladium and platinum can form partial bonds with other molecules. By forming these partial bonds, the bond in the actual molecule gets weaker and weaker and hence, the bond becomes easier to break. Let's say for example a hydrogen molecule. There is a single bond between the 2 hydrogen atoms. Platinum/palladium will form partial bonds with the 2 hydrogen atoms. By doing so, the single bond BETWEEN THE 2 HYDROGEN ATOMS gets weaker and weaker. Hence, a smaller amount of energy is needed to break the bond between the 2 hydrogen atoms (the hydrogen molecule). As the amount of energy needed to overcome the bond between the 2 hydrogen atoms gets smaller, we say the activation energy for the reaction has been reduced. Hence, a greater amount of bonds in hydrogen molecules can be broken in a smaller time, and therefore, we say palladium/platinum has catalysed the reaction.
- Q: Like biological and industrial reations. Thanks.
- Reactions that have high Activation Energy need catalysts to speed up reactions. These reactions aren't spontaneous since the reactants do not have enough energy to overcome the activation energy barrier. Catalysts are compounds that speed up reactions by providing an alternative pathway for the reaction. It is a common misconception that catalysts lower the activation energy. It doesn't actually lower the activation energy, instead it provides an alternative pathway with lower activation energy. For example, breakdown of hydrogen peroxide happens in nature but, relatively slowly. When you add a little bit of manganese dioxide, the breakdown happens a lot faster. Another example is, breakdown of glucose in the body. It is facilitated by an enzyme called amylase (or carbohydrase). An industrial example is the use of vanadium pentoxide (V2O5) in the Contact process, where SO2 is converted to SO3 in the presence of V2O5. Hope that helps!
- Q: Is the reaction of the exhaust purification of cars (carbon monoxide and nitrogen
- NO + 2CO = 2CO2 + N2 reaction is exothermic. Conditional catalyst
- Q: How do I write about the ion equation?
- 4NH3 + 5O2 == 4NO + 6H2O
- Q: Could God be Discribed as a Catalyst?
- Whether we agree with them or not, many people are driven by concept of god(even those trying to disprove god). So, yes, at least in part, 1 could describe god as a catalyst.
- Q: The size of △ H in the thermochemical reaction equation is related to the use and unused catalyst
- There is no relationship between the catalyst can only change the reaction rate
- Q: Chemical reactions in the presence of impurities will cause catalyst poisoning, how to understand this sentence
- This is in the chemical balance, but also alone
- Q: What are the catalysts?
- The catalyst is a substance that can change the rate of the reaction without changing the standard of the reaction Gibbs free, according to the definition of the International Pure and Applied Chemistry (IUPAC) in 1981, Enthalpy change. This action is called catalysis. The reaction involving the catalyst is a catalytic reaction. The catalyst will induce a chemical reaction to change, causing the chemical reaction to become faster or slower or to undergo a chemical reaction at a lower temperature The catalyst is also known as a catalyst in industry, and the composition, chemical properties and quality of the catalyst itself do not change before and after the reaction;
- Q: 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.
