- Q: A biological catalyst or a chemical reaction facilitator is know as a/an?
- I was always taught that it was something best learned by putting forth a bit of effort, reading a bit and embedding the info in your brain so you will remember it always. Just me I guess.
- 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?
- In fact, my understanding is to participate in the reaction, but in the whole process of reaction is both a reactant and a product. But in the reaction process is to participate.
- 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: The best use of chemical catalysts
- Do not know what you want to use the best thing is what the catalyst is generally used in the process, there will be an initial induction period, the catalytic activity is relatively low, and then reached a stable catalytic state, this paragraph is generally called the catalyst life, the final Due to poisoning, active ingredient aggregation and so on factors, the catalyst activity will be reduced, then need to replace the new catalyst
- Q: Can some chemical reactions have a variety of catalysts that are correct or wrong?
- Very correct, many reactions can have a lot of catalyst. Such as hydrogen peroxide decomposition can be used manganese dioxide or fe destroy
- Q: What are the characteristics of the catalyst in the chemical reaction?
- In simple terms: the catalyst itself is involved in the reaction, the quality of the reaction before and after the same, the ingredients do not change. The catalyst can change the rate of chemical reaction, increase the rate of reaction called catalyst, slow the inhibitor.
- Q: What is the difference between biological enzymes and chemical catalysts?
- The biological enzyme is a class of molecules with moderate molecular weight in the living cells. It is a natural macromolecule catalyst in nature because the enzyme and the reactants are more specific than the reaction of the catalyst with the chemical synthesis of the catalyst (1) High efficiency (2) selectivity good by-product less (3) mild reaction conditions and so on
- Q: about 1-3 sentences on this will do thank you
- since enzymes are found in the body,earlier they were belived to be related to life processes. however the organic molecules can also be produced outside the body through inorganic processes. a catalyst helps in speeding up the reaction.here the enzymes play as catylyst in the body for various metabolic pathways.
- Q: What is the difference between biological and chemical catalysts?
- Biological catalysis involves an enzyme usually working in conjunction with a co-enzyme. These enzyme/co-enzyme systems are highly specific and are usually only effective for one reaction. Catalysis of non biological reactions is usually much more general and any one catalyst will be effective in many reactions.
