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: No one knows the expression of the catalyst and the chemical expression of the acridine: In organic reactions, the catalyst is complex and consists of several or more. Write Chinese characters directly.

Q: Chemistry is often said that the catalyst can change the material reaction rate, rate and speed What is the difference: Rate refers to: the amount of time in the unit reaction, and speed, and the speed simply refers to the speed

Q: The "one-to-two change" of the catalyst is that the quality and chemical properties of the reactants are constant or the quality and chemical properties of the catalyst are constant?: The morphology of the catalyst may change before and after the chemical reaction, but the quality and chemical properties of the chemical reaction do not change before and after the chemical reaction. It is noteworthy that this does not mean that the catalyst is not involved in chemical reactions. Some chemical catalysts are involved in chemical reactions, but in the form of intermediates, consume a certain amount of catalyst in a chemical reaction, but in the subsequent chemical reactions, the same quality of the catalyst will be produced. On the whole, the quality of the catalyst before and after the chemical reaction is not changed.

Q: How does catalyst aid a chemical reaction?: A catalyst will lower the activation energy of a reaction, and hence allow it to happen faster. The actual mechanisms vary widely. Two mechanisms are: 1/ formation of intermediate compounds, which can then decompose into the catalyst and the required product 2/ provision of a large surface area for adsorption, so the reactant molecules can come into contact sooner.

Q: Will the chemical catalyst not reduce that?: Why is it done? Although the catalyst does not react chemically, the catalyst itself is deteriorated and is not always used

Q: What is the catalyst for industrial aluminum electrolysis?: 2AlCl3 (melt) = power = 3cl2 + 2al by-product is chlorine

Q: Why can some catalysts be reused in (chemistry)?: Because the catalyst in the chemical reaction before and after the quality and chemical properties have not changed, so in the chemical reaction can be reused.

Q: What is the relationship between the catalyst and the chemical reaction? What is the relationship between the enzyme and the catalyst?: Catalytic, also known as catalyst, is defined in the junior high school stage to be able to change the rate of chemical reactions, and its own quality, composition and chemical properties remain constant before and after chemical reactions. For example, manganese dioxide can be used as hydrogen peroxide (hydrogen peroxide) decomposition of the catalyst. The catalyst is divided into the positive catalyst and the catalyst is used. The positive catalyst contributes to the reaction to move in the positive direction, and the reverse catalyst contributes to the reaction to move in the reverse direction.
