- Q: On the issue of chemical balance and catalyst
- Because the rate is scalar, it is not advisable to think too much from the speed change. I mean kv meaning that is proportional to the relationship, rather than proportional function relationship.
- Q: Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- The catalyst is only a catalytic role, not directly involved in the reaction, the current principle of its role is not clear
- 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: what is metallocene catalyst technology?
- Metallocene catalyst A transition-metal atom sandwiched between ring structures having a well-defined single catalytic site and well-understood molecular structure used to produce uniform polyolefins with unique structures and physical properties. See also Catalysis; Coordination chemistry; Coordination complexes; Metallocenes; Organometallic compound. In the early 1980s, W. Kaminsky discovered that an appropriate co-catalyst activated metallocene compounds of group 4 metals, that is, titanium, zirconium, and hafnium, for alpha-olefin polymerization, attracting industrial interest. This observation led to the synthesis of a great number of metallocene compounds for the production of polymers already made industrially, such as polyethylene and polypropylene, and new materials. Polymers produced with metallocene catalysts represent a small fraction of the entire polyolefin market, but experts agree that such a fraction will increase rapidly in the future. See also Polymer; Polymerization; Polyolefin resins.
- Q: What is the maximum impact of the chemical reaction rate? Such as catalyst, temperature, concentration. If you can, you can row order.
- The catalyst certainly affects the most
- Q: I dont know what it is but when i open up my computer it comes up and it says that its not working? so i really dont know what to do.
- ATI Catalyst Control Centre is a control program for ATI graphics cards. If you have an ATI graphics card, go to the ATI website and download and reinstall the program.
- Q: What is the reaction in chemistry?
- Industrial production of ammonia, ethanol, industrial synthesis of ammonia, ethanol catalytic oxidation, acetaldehyde oxidation into acetic acid, ethyl acetate preparation, the transformation of automobile exhaust, benzene substitution reaction and addition reaction, some other addition reaction of hydrocarbons, Ethanol dehydration to produce ethylene and so on
- Q: Please name 2 common examples of catalysts.Thank you?
- Common Catalysts
- Q: Does increasing the amount of catalyst added to, say, a solution of Hydrogen Peroxide, make the rate of reaction go faster. Is the rate of reaction directly proportional to the amount of catalyst added to the solution? Or does the experiment go at the same rate regardless of how much catalyst there is? Thanks would really appreciate some answers. - Sarah
- Adding a catalyst would increase the rate of reaction. This could decrease the activation energy, the amount of kinetic energy needed for the reaction to occur. Hope that helps
- Q: Can you describe at least 4 ways a catalyst can lower the activation energy of a reaction?
- To see how a catalyst accelerates the reaction, we need to look at the potential energy diagram shown below which compares the non-catalytic and the catalytic reaction. For the non-catalytic reaction, the figure is simply the familiar way to visualize the Arrhenius equation: the reaction proceeds when A and B collide with succificient energy to overcome the activation barrier. The change in Gibbs free energy between reactants, A + B, and the product P is delta G. The catalytic reaction starts by bonding of the reactants A and B to the catalyst, in a spontaneous reaction. Hence, the formation of this complex is exothermic and the free energy is lowered. There then follows the reaction between A and B while they are bound to the catalyst. This step is associated with an activation energy; however, it is significantly lower than that for the uncatalyzed reaction. Finally, the product P seperates from the catalyst in an endothermic step. The energy diagram illustrates 4 ways the catalyst works : The catalyst offers an alternative path for the reaction that is energetically more favorable The activation energy of the catalytic reaction is significantly smaller than that of the uncatalyzed reaction; hence the rate of the catalytic reaction is much larger The overall change in free energy for the catalytic reaction equals that of the uncatalyzed reaction. Hence, the catalyst does not affect the equilibrium constant for the overall reaction. A catalyst cannot change the thermodynamics of a reaction but it can change the kinetics. The catalyst accelerates both the forward and the reverse reaction to the same extent. In other words, if a catalyst accelerates the formation of product P from A and B, it will do the same for the decomposition of P into A and B.
