Q:Hydrogen and oxygen in the role of the catalyst can do the chemical formula of aviation fuel?
You two yeah? Meaning that hydrogen is ignited in oxygen to release energy to push the rocket forward, as the catalyst for those who love,
Q:What is the difference between electrocatalysis and general chemical catalysis?
General chemical catalysis is a catalyst, and electrocatalysis also need to be carried out under the conditions of the electric field
Q:What is a chemical catalyst?
A substance that participates in chemical reactions but does not change the quality and chemical properties. It can change the reactant activation energy, speed up or slow down the reaction rate.
Q:catalyst question?
The purpose of a catalyst is to provide an alternate pathway for a reaction to proceed, often one with a lower activation energy, such that the reaction will generally proceed faster. The key to catalysts if they they are NOT consumed by the reaction in the end (they may be consumed in an intermediary step, but if so, a subsequent step will recreate the catalyst). In other words, catalysts do not actually participate in the reaction, so they may be reused when the reaction has completed.
Q:Comparison of biocatalysts with chemical catalysts!
The same point: biocatalysts and chemical catalysts are selective (specific) and efficient; participate in each reaction, its own nature and quantity will not change.
Q:What are the methods of catalyst characterization?
Physical means, is commonly used detection means, infrared, ultraviolet, electron microscopy, X-ray diffraction, nuclear magnetic, etc., of course, including a variety of conventional inability analysis.
Q:What about the chemical reaction of the catalyst if there is no catalyst?
The reaction rate will change
Q:What is the nature of the catalyst before and after the chemical reaction?
Yes, the catalyst only acts as a catalyst and does not participate in chemical reactions
Q:The chemical reaction equation of methanol heating and oxygen in the presence of catalyst
Catalytic oxidation of formaldehyde
Q:Biology Question - Catalysts?
Organic or Inorganic - the catalyst (enzyme) must be organic to be found in the cell. Catalysts speed up chemical reactions inside a cell and must therefore be organic to be a functioning part of the cell. Reusable - There are so many reactions that catalysts are involved in that it would be a waste for the cell if a catalyst could only last one reaction, especially if there are inhibitors and competition for the active site. Catalysts must be reusable in order to keep the cell functioning. Catalysts always remain unchanged after a reaction. HIihly Specific - Catalysts are only made to catalyze one specific chemical reaction. Their active site has proteins bonded in such a way that only certain elements can enter the active site and H bond with those proteins. The fact that they are highly specific maximizes the productiveness of the cell. And it ensures that the cell only has catalysts to reactions that it needs to be completed. It also ensures that the elements are correctly bonded with eachother. If any two elements could enter the active site, there is no guarantee that the correct product will be produced. Catalysts and Enzymes must be super highly specific in order to properly function. Lowers Activation Energy - The more energy a cell has to spend to catalye a reaction, the worse it is for the cell and the less ATP is has for other reactions. Catalyts hold the substrates together so there is less energy that is needed to have the two substrates react with eachother. Activation Energy is the energy that is needed to start a reaction. So the less energy used by the cell for reactions, the better for the cell. Hope this helps
