- Q: When there is a catalyst in the chemical equation, it is not necessary to match the atoms of the catalyst
- No need, because the catalyst in the chemical reaction before and after the quality of the same
- Q: Characteristics and types of catalysts?
- Catalysts don't undergo any change. and types of catalysts - 1) Homogeneous Catalysts ( Having same phase that of reactant, product i.e. reactant and product and catalysts all are either liquid or gas or solid.). 2) Hetrogenrous Catalysts (Different Phase than that of reactant and product. 3) Autocatalysts (reaction proceed catalysed as product is formed or product catalyse the reaction.)
- Q: Chemical questions: "CO2 and H2 in the catalyst conditions have a reaction, the reaction of the chemical equation is"
- CO2 + H2 = CO + H2O (conditions: catalyst, generally requires heating, and reversible)
- Q: Chemistry why the catalyst can be equal to speed up the positive reaction rate
- Since the catalyst only changes the activation energy and the amount of reactivity can be reduced, the amount of reaction energy is also reduced. Therefore, a positive catalyst is also a good catalyst for its reaction. Speed up the same multiple.
- Q: Why the catalyst is required to have a large surface area and a rich pore structure
- So that the use of more fully catalyst, the effect is better.
- Q: What suitable catalysts can I use for the reaction between Hydrochloric acid and zinc metal?
- Something that can cause a reaction, speed up or slow down a reaction, without changing itself.. structure yea..
- Q: The last question asked no one answered this question.
- First of all now the most common way to change the ligand.
- Q: In biology, the enzyme seems to be a tool for opening a reaction, such as the decomposition of cellulose, such as linked RNA and protein, no enzyme can not. But in chemistry, the catalyst is only a regulatory role, change the reaction rate only. The teacher said that the enzyme is the catalyst. Is there any other effect of the enzyme? (Ignorant high three dogs, you do not spray the big god)
- In fact, the chemical reaction is from the substrate (S) to the product (P). The chemical reaction is from the substrate (S) to the product (P). The chemical reaction is from the substrate (S) to the product (P) the process of. However, there is a free energy barrier between S and P, and in the absence of a catalyst, it is difficult to step through it and will pull something about it. Or understood to want you to jump 3 meters high, it is simply to life.
- Q: Nitrogen and hydrogen in the role of high temperature and pressure catalyst to generate ammonia chemical equation
- N2 + 3H2 = catalyst, high temperature and high pressure = 2NH3
- Q: Does all chemical reactions have a catalyst?
- Not some reaction without catalyst
