- Q: Why the amount of catalyst is too small will make the chemical reaction rate slowed down
- Whether the chemical reaction can be carried out according to the change of free energy, but only according to the change of free energy can not determine whether the reaction can be completed, because the chemical reaction is also completed by the reaction of the energy barrier, that is, if the reaction energy barrier is high, To provide some energy, across the barrier, to complete the reaction. The energy barrier is called activation energy. And the role of the catalyst is to reduce the activation energy, so that in a relatively harsh environment, chemical reaction occurs.
- Q: Does the catalyst participate in chemical reactions?
- Do not participate in the reaction, before and after the reaction of the quality of the material properties have not changed
- Q: Why the catalyst after the chemical reaction of its quality and chemical properties unchanged
- In fact, the catalyst reaction also enters, which changes the rate of positive and negative reactions ... enhances the reactive molecules of the reactants, thereby changing the reaction rate ...
- Q: Always speeds the reation ratedoes not affect the reation rateundergoes a chemical changedoes not become part of the chemical changealways slows the reation rate
- the BEST ans is does not become part of the chemical change!!!!! *Defination of catalyst:catalyst is a chemical substance that will CHANGES the rate of reaction.it does not undergoes any chemical changes catalyst affect the reation rate!!! catalyst can divide into positive and negative catalyst so it can changes(either SPEEDS or SLOWS) the reaction rate
- Q: Is the catalyst in the field of inorganic chemistry?
- In particular, the chemical and homogeneous catalysis of inorganic chemistry has deep origins. Inorganic chemistry, oxides (such as metal oxides), family elements (such as the chemical behavior of transition metal elements) can be provided for catalytic science Support and guidance.
- Q: The greater the chemical adsorption strength, the catalyst activity changes
- If the adsorbent is a reactant, then the better the adsorption capacity of the better catalytic effect; but the catalyst surface of the product will generally have adsorption, if this effect has become very strong, then desorption The process will become difficult, the catalytic effect will decline; the other one, if the adsorption of other substances, such as the reaction may produce a reaction or the catalyst will poison the material, it is greatly detrimental to the catalytic effect. The effect is to be controlled in a suitable optimum range for superior, and preferably to be selectively adsorbed.
- Q: The last question asked no one answered this question.
- This problem is difficult to answer comprehensively because the study of the different directions of the catalyst is different.
- Q: CO and NO react under the action of a catalyst to generate chemical formulas for CO2 and N2.
- C from +2 to +4 price 2e * 2
- Q: Especially how can i explain the experiment with a paper and 2 paperclips with the paper acting as the catalyst.
- A catalyst acts on one material to activate it towards reaction with another material that it would not otherwise spontaneously react with (it lowers the reaction's activation barrier). For instance, the 2 paperclips may not want to react with each other, but if the paper attaches to one, it becomes more reactive and it will now clip onto the other paperclip. The catalyst then leaves (paper is detached) which is called catalyst regeneration, which goes on to activate another molecule in the same fashion. A common example is using Lewis acid catalysts to activate carbonyls by coordinating to the oxygen so that the the carbon becomes more electrophilic for attack by some nucleophile.
- Q: Word editor when playing chemical equation = with the above conditions or how to adjust the size of the catalyst, how to make it centered,
- Open the word - insert - object - WPS3.0 formula - and then select the "label arrow template", you can add a catalyst.
